Fourth day:

Migrations for game app have been resetted.
Migration for token types and token conversions.
Now using the canonical Match.get_absolute_url() instead of url().
Separated MatchPlayer.setup_ready (renamed from ready) and PlayerInTurn.ready so original values can be kept showing turns passing for unready players.
Several improvements on models.
Game transition from STATUS_SETUP to STATUS_PLAYING implemented.
Several TODOs added.
Removed original repower app.
