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.

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

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.

show admin menu and list for users who are admins of repos.

- this is consistent with user groups, repo groups displaying.
- fixes 403s after you actually delete a repository being it's admin

Do read only checks on attach as fork of repo list.
We shouldn't leak repo names here to which we don't
have access

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

recursive forks detach
- added API attrs for option to delete or detach forks
- deleting repos with attached forks raises an special Exception

#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

Pass in old groups data to CanWriteToGroup validator for later skipping group checks.
This will be a part of refactoring done to do user permissions changes without messing with main
repo form data

Pass in old groups data to CanWriteToGroup validator for later skipping group checks.
This will be a part of refactoring done to do user permissions changes without messing with main
repo form data

"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.

implemented #689 Deleting Repositories with Forks Should Be Easier
- optionally detach or delete forks associated to repo

move permission check of write access to repo groups inside a form.
- it's runned via create/edit/fork forms
- in case we have disabled repo creation, it will check root location write access for people that are not super admins, or have explicity create repo permission
- in case there's a group value passed to form, it checks just admin or write access

Implemented #738 Giving a user WRITE+ permissions on folder should not allow repo creation in root folder.
user can create repos only if he got explicitly permission for creating repos globally, or have WRITE+ permission on a group.
Then he can create repositories inside this group

repository extra fields implementation
- verion bump to 1.6
- migrations

filter out repo groups choices to only ones that you have write+ access to. Before it was read+ access and you got proper
error saying that you don't have write permissions to group to create repo in. Filtering out the read groups is less confusing for users.
ref #730

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

Fixed some issues with edit form
- unified code (but still a lot of duplicated code left over)
- fixed forms
- fixed validators

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

Implemented permissions for writing to repo
groups. Now only write access to group allows to create a repostiory
within that group

Implemented basic locking functionality.

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

merged + fixed pull request #62: Implemented metatags and visualisation options.
- new tag lang
- fixed found issues
- added simple test

rewrote admin repos page.
- less info (no VCS data), but much faster.
- having 1000s of repos is not a problem now
- pagination/filtering using YUI datatable

sqlalchemy sessions cleanup in admin
Cleanup settings options

Fixed issue #501 error on setting set_as_fork to same repo
- also fixed html fill select set
- wrote set of tests for that option

Readme renderer now uses landing_rev parameter to render the readme based on
given revision, rather than tip

New repo model create function
- fixed some sessions calls

Initial version of landing revisions ref #483
- fixed relevant tests for creation of repo
- added some tests for git

Implemented #467 Journal logs comments on changesets
- added created/updated user action to journal
- added created/updated users group action journal
- added ip adresses to most of action_log calls to track IP changes
- rewrote action_parser to simpler and more efficient solution

#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

- fixed issue with missing commits on some repos commands
- fixed issue with parsing commits for stats when there were only two commits

Added handling of ignore whitespace flag in changesets
- fixed messages for FK validation

commit less models
- models don't do any commits(with few exceptions)
- all db transactions should be handled by higher level modules like controllers, celery tasks

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

fixes #288
- added group management into non admin repo settings form
- fixes also issues with groups after API codes merge
- all tests passes ok.

unified generation of repo groups choices
added on-the-fly conversion to new repository groups format (supporting path as a link)

fixes #200, rewrote the whole caching mechanism to get rid of such problems. Now cached instances are attached
to db repository instance, and then fetched from cache. Also made all current test work.

#47 implemented Adding of new repo_groups+forms+validators. Fixed sorting of repo groups by main names in multiple locations. Removed some unneeded calls to self.sa for exchange to .query() methods.
Added new db unique key for Group

fixed saving settings on repositories inside groups, also fixes #187
added options to properly rename directories in groups

#109, added manual pull of changes for repositories that have remote location filled in.
This also logs this action in journal

#109, added optional clone uri when creating repo.
Cleaned up repos controller moved common code into __load_data
