Finished events controller
Old test passing, created comments and relations
Created comments model and added user associations
Adding fake comments
Created comments controller
Fixed event comments

Comments are added as nested resources for events. Form and controller
have been modified to reflect this. Removed validations on user_id and
event_id since they prevent comment creation and are unnecessary since
this functionality is handled by ActiveRecord. Removed unnecessary test
cases covering missing user_id and event_id.
Updated models and spec annotations with annotate gem
Merge pull request #52 from Vunovati/event_comments

Event comments added. Events still need work - association with bands and locations needed
