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

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

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

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

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

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