Alan Bradburne 4f0354303f Improve channel, user and api_key models with basic scopes, correct references and protect attributes.
Simplify channels & user controllers and models, moving code to the models.
Remove catch-all route and ensure all actions are specified, fixing url paths.
Change clone to dup in feed_controller as using clone seems to affect the cloned object (problem only in ruby 1.9.3?)
