Use AJAX for review posting.
Added pry to gemfile. Ajax handles save failure too (and added validation to prevent blank comments).
Disables button during save and reactivates on ajax completion
Implemented ajax for message deletion
Reorganized css and js files and deleted coffeescript files.
Changed ajax for new message to append instead of refreshing all messages.
Restricted rails_12factor to production. Desired by heroku but causes line duplication in console.

Hooked up jquery color plugin and used it to flash color on newly posted messages.
