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
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.

Fixes #852, created custom Flash() class and Message
transport class to overcome issues with unicode errors.

moved make-index command to paster_commands module

- optimized imports and code

Switch gravatar to always use ssl.

- there's no reason why not to.
- removed thread locals imports thanks to that
- use internal RhodeCode config for alternative gravatar url

diff parser: redefined operations stats for changes

- don't loose info about multiple operations like rename + chmod
- new Binary flag when dealing with binary file operations
- fixed diffs after mercurial 2.6 when GIT binary diffs were fixed
- added more tests for multiple operations

- refactored the way diffprocessor returns data. It's
now easier to extract type of operation on binary files
- diffprocessor doesn't append that information into the diff itself

Unified the paginators for pylons and YUI.
- YUI based paginators now behave more like the ones generated with pylons
- introduced new custom pylons paginator for customizations needed to unify both

config: rename options to show_revision_number and show_sha_length

'sha_show_numeric_rev' had nothing to do with the sha value.

The revision numbers are kind of native to Mercurial and there they are known
as 'revision numbers'.

'sha_len' was very short and didn't clarify that it only controlled what was shown.

These settings are currently only used in the changelog, but they should be used everywhere.

Adding the context bar too all pages related to a Repository.
Deleted top menu items that are on the context bar already.

revision extraction function shouldn't be so eager, just extract commits that are
surrounded with spaces, or they are at beginning of the whole string
- wrote tests for that
- used parametrized for other tests

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

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

Implemented better support for Wildcard queries
add username column to journal for caching logs after user deletion
added tests for admin journal
migrations

fixes #645 Fix git handler when doing delete remote branch
- journal will now display nicer labels for create tag, and delete branch operations for git

Implemented generation of changesets based
on whole diff instead of per file diff. That
can give a big speed improvement for large changesets in
repositories with large history.
- improved handling of binary files
- show renames of binary files
- implemented new diff limit functionality
- unify diff generation between hg and git
- Added binary indicators for changed files,
- added diff lib tests

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

don't check for url issue links, since we always want to linkify changeset into a repo link, fixes issue
with issue_pat beeing disabled breaks the urlification

#518 multiple issues patterns
- added logging
- some code cleanup
- added example of wiki pattern to .ini file
- updated contributors and changelog

Allowing multiple issue servers to be autolinked in the changeset view;
linking is now contingent on issue_server_link, issue_pat and issue_prefix
being defined; multiple servers can be used by specifying a common suffix on all
the above variables, ie ..

issue_server_link_1
issue_pat_1
issue_prefix_1

.. and ..

issue_server_link_other
issue_pat_other
issue_prefix_other

.. would be treated as two distinct servers, but ..

issue_pat_thing

.. would be ignored (since the other two requisite vars aren't present).

This patch is backwards compatible with existing variables (as a suffix
isn't needed).

Implemented patch from andrewsh ref #565 Add support for {netloc} and {scheme}
to alternative_gravatar_url

fixes issue #543, un-broken alternative gravatar option
- also now formatting is similar as other parts `{}`

Implemented #532.
- now displaying username + full name for mapped users from RhodeCode

Implemented basic locking functionality.

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

fixes issue #531, when extracting user email, we check it against the database,
and return user default email. Also if no email is present check the username
for matching targets.

Reimplemented file-browser using partial-ajax
- improves the speed of browsing of files for revision
- url push state via html5 History
- also cache the results of calls for even faster handling the content

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

- added action when someone closes pull request in journal
- fixed icons and links on pull request comment in journal

Added h.tooltip to all places that tooltip_title is used.
- improved escaping of < and > inside tooltips

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
