Removed profiles_controller

Rerouted the profile show to the users controller. Seems cleaner, &
DRYer.
Adding Following Functionality to the Users Controller

Added followers, following and follow method (Going to swap the follow
method for a direct post to the model using a form). Tidied up some
routing. Basic display of followers&following in the view.
Fixing routing errors on the User CRUD
Can now create and destroy relationships through the controller

Created a relationship controller. Form partials can follow & unfollow
other users. (Needs further testing)
