A little extra refactoring of LevelDB event store.
Use my fork of Hamster which includes fixes for marshalling hashes, and thus Hamsterdam derived objects.
Allow specification of LevelDB event store location via $EVENT_STOREDIR.
Shut down the event store cleanly on termination.
Use Synchronous writes with LevelDB.
Update Gemfile.lock.
Add missing require to ReviewBrowser.
Extract ReviewsApp into seperate file.
Extract CardEditorApp into seperate file.
Extract ModelEditorApp into seperate file.
