First step in two-part process to rename directories to kallithea.
This first step is to change all references in the files where they refer
to the old directory name.

Complete copyright notices for web interface; change footer to link to them.

The original copyright notice found in the footer was not accurate as it
included only one of the many copyright holders in this project. This change
creates an "about" page, which currently contains just the copyright and
license information. It links to repository for additional potential copyright
holders not listed on the about page.

Unlisted contributors are mentioned in template comments.

Html links for Kallithea is fixed and we link to Conservancy.

Display of version information in the footer is improved.

Imported some of the GPLv3'd changes from RhodeCode v2.2.5.

This imports changes between changesets 21af6c4eab3d and 6177597791c2 in
RhodeCode's original repository, including only changes to Python files and HTML.

RhodeCode clearly licensed its changes to these files under GPLv3
in their /LICENSE file, which states the following:
The Python code and integrated HTML are licensed under the GPLv3 license.

(See:
https://code.rhodecode.com/rhodecode/files/v2.2.5/LICENSE
or
http://web.archive.org/web/20140512193334/https://code.rhodecode.com/rhodecode/files/f3b123159901f15426d18e3dc395e8369f70ebe0/LICENSE
for an online copy of that LICENSE file)

Conservancy reviewed these changes and confirmed that they can be licensed as
a whole to the Kallithea project under GPLv3-only.

While some of the contents committed herein are clearly licensed
GPLv3-or-later, on the whole we must assume the are GPLv3-only, since the
statement above from RhodeCode indicates that they intend GPLv3-only as their
license, per GPLv3§14 and other relevant sections of GPLv3.

Allow RhodeCode maintainers to specify a custom bug tracker.

This allows people who maintain large RhodeCode installations to setup their
own bug tracker and respond to requests against their specific installation.
The maintainer is then free to forward problems with RhodeCode to the
canonical issue tracker on bitbucket.

If the config option "bugtracker" is present, its value will be used with the
"Report a bug" button. If left blank, this disables the button. If no value is
present, then the default is used. This is so that the new config option
doesn't break installations of RhodeCode upgrading to a newer version and to
allow easier installation for the common use case.

refactored url.resource to full definition of routes

- id -> gist_id

Implemented simple gist functionality ref #530.

- creation of public/private gists with given lifetime
- rhodecode-gist CLI for quick gist creation

Removed shortlog aka lightweight changelog.
Current version of changelog is fast and condensed.
There's no sense to keep changelog duplicity.

Use changelog controller for displaying history of files.
step 1 for removing obsolete shortlog

consistent handling of grant/revoke of permissions widgets
- use 1 method for users and for users groups
- use common JS for ajax revoke
- cleanup code

- Manage User’s Groups: create, delete, rename, add/remove users inside.
by user group admin.
In this case, a user's group can be owned by several people thru an owner user's group.

Some refactoring of naming, permission handling logic.
- remove some code duplicity as well as inconsistent naming

#749 and #516 Removed dupliciting of repo settings for rhodecode admins and repo admins
- repo admin now is allowed the same set of operations as the rhodecode admin
- single logic for forms/validations/permissions
- fixes #805 update external repo via webinterface
-

moved permission management into separate entity.
- this solves issues when whole form submision could influence permission management
particular case is that when repo group permission is revoked and user is no longer able to update repository settings

files: accept URLs with no path and no slash after the revision

This kind of URLs will frequently be edited by hand and trailing slashes are
usually just ignored.

better detection of deleting groups with subgroups inside.
Added less strict checks on delete group routing so we can delete zombie groups
(those that are not in filesystem but in DB)

"Users groups" is grammatically incorrect English - rename to "user groups"

- and same story with "repositories groups"

This will only change the user facing texts. Names of files, modules, functions
and variables should be changed too.

compare: swap org and other when they refer to different repos, ie are pull request style

Pull requests will have a different from/to description - but in a consistent
and slightly better way that can be improved later.

A pull request diff is empathic: "How will this look for the peer I'm proposing to" style.

repository extra fields implementation
- verion bump to 1.6
- migrations

summary: don't link explicitly to /summary

It is redundant and exposed ambiguous urls.

Group management delegation:
this allows users to become an admin of groups
a group admin can manage a group, change it's name
or permissions. A group admin can create child group
only within a group he is an admin off.

Top-level group can be only created by super admins

Use common function for generation of grid data
- admin grid now has dedicated edit button, and uses changeset_cache
- some small improvements to grid
- all other datatables use this

Added UserIpMap interface for allowed IP addresses and IP restriction access
ref #264 IP restriction for users and user groups

Implemented #379 defaults settings page for creation of repositories
- locking
- statistics, downloads
- repository type

Implemented file history page for showing detailed changelog for a given file
- fixed git detection of filenode history when executed on directory
- shortlog uses urlify_commit function now

implements #636, lazy loading of history and authors to speed up page responsiveness.
- loading full history is not always needed, and it's very heavy operation. Now this is lazy loaded
when clicking on button

new patch function, and urls schema.
now rhodecode generates
- diff
- plain diff
- patch files

both for git and hg

new tooltip implementation
- added lazy loading of changeset tooltips for journal data

fixed issue #559 fixed bug in routing that mapped repo names with <name>_<num> in name as
if it was a request to url by repository ID

Implemented basic locking functionality.

- Reimplemented how githooks behave
- emaulate pre-receive hook
- install missing git hooks if they aren't already in repo

switched repo_name to non greedy match.
In some cases greedy match can confuse routes system, and return 404 for valid urls

Merged pull request #56
- fixed issue with resolution of ref_types for mercurial
- now properly handles ref type
- added option to compare by specific revisions also

Improvements to my account page
- lazy load repositories via ajax results in much faster page load
- added pull requests tab to see my pullrequests and the ones i participate in
- new style tabs

- added commenting to pull requests
- it's now possible to change pull request status via changeset status option
- status flags with associated pull requests are links to pull request they been
changed in

- pull request generates overview based on it's params
- added page to show all pull-requests for a repository
- db schema changes to support comments and inline comments for pull-requests

Added basic models for saving open pull requests
- added pull-request models
- added pull-requests notifications into inbox

public journal feed updates. fixes errors
- changed the urls to more friendly looking public_journal/rss|atom
- old one will still work for backward compatibility

#227 Initial version of repository groups permissions system
- implemented none/read/write/admin permissions for groups
- wrote more tests for permissions, and new permissions groups
- a lot of code garden, splitted logic into proper models
- permissions on groups doesn't propagate yet to repositories
- deprecated some methods on api for managing permissions on
repositories for users, and users groups

#235 forking page repo group selection
- group is selected as parent repo
- refactoring of session behavior to get more atomic operations in models

Notification system improvements
- deleting
- tests
- ui
- moved to separate controller

#71 code review
- added delete of comments by owner or admin

#77 code review
- initial very simple version of changeset comments
- RST parsed

lazy load of branches and tags menu
- to reduce load on repositories with large amount of branches and tags.
- reduce load times of pages significantly on large repos

implements #226 repo groups available by path
fixes #259 Groups with the same name but with different parent group

Fixed methods for checking if path in routes is a repo
added method for checking if path in route is a repos_group
