Dropping db fixed state issues (?) and got buttons working
1-click Prereg working when signed-in
merged master into Preregistrations and fixed conflicts
Added preregistration not as modal
Removed prereg & login modals
fixed cancel application, added has_many work_signups to user model so we can call current_user.work_signups in the workshops controller to display my signups on the workshops index
