Made initial commits for new moderation user interface: added moderate buttons to submissions#index, added popup forms, wired up actions
Resolving Gemfile.lock merge conflict
Turned moderate_form into a remote; added update.js.erb for submissions_controller; wired up transitions so that approve and deny happen using ajax
Merge branch 'new_moderation_ui' of github.com:concerto/concerto into new_moderation_ui
Removed moderate_form partial (changed to moderate_tile_form); began to wire up Approve and Deny from submissions#show. Please note that Deny is currently NOT FUNCTIONAL from the submissions#show view - need to figure out how to properly submit the form along with the parameters.
