Version bump.
Add User entity to Core Data.

This is largely to pave the way for user profiles, whose data makes no sense
stored elsewhere.

Core Data's lightweight migration handles adding the new entity and removing
the old attributes. However, rendering posts and viewing thread lists offline
will be messed up until the next refresh occurs in the app. I consider this
tradeoff worth not writing custom migration code.
Add and parse userID attribute.

So we can use it to look up profiles, send PMs, etc.
Reorder files in xcodeproj.
Fix parsing tests.

Been rearranging parsing classes and haven't run tests in awhile, so they
broke.

Add Comedy Gas Chamber stylesheet
