- fixed issue where user-submitted release date info with "upcoming" checked was getting hosed
- fixed issue where "release" shortcut for the "date bought" widget in the collection UI wasn't showing up when you click "Add to collection" (though it would show up when you refresh the page)
- added validation steps to the "date bought" text input in the collection UI. You now get warning pop-ups if you try to enter either an invalid date (ie. "14/03/foo"), or a date that is earlier than the release date
- finished keen new API system (no visible changes to the site, but it will make my life easier)
