Authorization

Mostly authorization stuff but there are others, too. Basically all of the pages on the diagram is done, except for the add repo page. Repo authorization may or may not work!

Also, the home page is rendered with `users#show` when the the user is authenticated. This is done with [Advanced Constraint](http://guides.rubyonrails.org/routing.html#advanced-constraints). Neat stuff!
