@chompomonim status update for this task.

During refactoring I found mps_v2 and widget quite heavily relies on CouchDB and without refactoring it there is no way to use MySQL for new test, because it would brake mps_v2 and widget, because they expect to find topics, members of parliament and votings in CouchDB.

So far, after working on this for 12 hours, I managed to fix all failing tests, move crowled data to MySQL, and make overall website work, but there are still few places left, that was not covered with tests. After fixing all places found during manual testing it will be done.

Currently no code was pushed, because I refactored many places and change a lot of code upside down. After I finish, there will be no sign of CouchDB or django-sboard, it will be vanilla Django.

Thinks that I tested more or less work, but still there might be some issues, let me know if you find anything. Now there is no need for CouchDB or django-sboard, everything was wiped out. See commit messages for more details.

@menesis I'm giving you a green light with other tasks.
