Get rid of rails 4 deprecation warnings:
* .scoped has become .all
* implicit table joins need .references
* scopes need ugly lambdas
* get rid of whiny nils. I hated them.
* secret_token is now secret_key_base
Fix specs for EventsController

* Make stuff attr_accessible on Event
Make all location attributes on the form accessible
Fix rsvps_controller specs by fixing accessible attributes on rsvp and rsvp_session.
Fix migration madness
