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

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

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

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

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.

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.

Fixes for release 1.1.4
