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.

changelog: use unknown branch names as revisions

Makes the system more resilient

branch selectors: show closed branches too

It would be even better if they were fetched dynamically somehow and perhaps
placed in a sub sub menu ... but showing them in the list is often better than
not showing them at all.

Added missing __get_cs_or_redirect method for file history.
Fixes issue with displaying a history of file that is not present at tip.

moved make-index command to paster_commands module

- optimized imports and code

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

auth decorators are not used anymore on __before__
- this will allow to create a whitelist of API enabled controller functions
- moved around functions with _ to beginning of the files to make it cleaner

changelog pagination with branch filtering now uses
common logic that non branch filtered version.
- introduced CollectionGenerator object as a helper for
achieving abstraction layer on top of filtered results

Fixed calls to Session in db model
- added inject_ui method that should be later used for all injections of extra parameters into ui
- fixed naming conflict of `comments` functions and relationship that had the same name

Unified DAG generation for hg and git
- also fixes issue #470

Added number of comments in changelog for each changeset
- significantly improved speed of changelog page for large repos

revert default to 20, for large repositories it's better to go less and have it faster.
This is still saved in user session so everyone can set high number and have it saved while logged in.

implemented #44 - branch filtering in changelog, aka branch browser
- changed GUI on tags/branches to not use images.

fixed issues with python2.5
added compat module to rhodecode to have one point of fetching backward incompatible libs.

changelog uses lazy loading of affected files details, in some scenarios this can improve speed
of changelog page dramatically especially for larger repositories.

another major codes rewrite:
- created BaseRepo controller for all repo specific controller, and added common data propagation
- removed obosete codes, and made optimizations, removed to often calls to RepoModel
- fixed found bugs in files controller that generated unhandled 500 errors
- cache issues
- removed repo_branches global template values
- journal fixes
- main repo list is fully dict now it's less resource heavy that way

another major code rafactor, reimplemented (almost from scratch)
the way caching works, Should be solid rock for now. Some code optymizations on scmModel.get() to make it don't load unneded things. Changed db cache to file that should also reduce memory size

Code refactor for auth func, preparing for ldap support
css updates.
turned off graph,and branches for git changelog

Refactor codes for scm model
Some test updates, added test for admin user controller

Fixes for raw_id, needed for git
Renamed hg controller to home
css html changes

Code refactoring,models renames
cleaned up sqlalchemy sessions,
added cache support to most queries in models
fixed test.ini file

#37 fixed json imports for python2.5
removed cache manager settings out of meta to ini files
docs update.
