<p>This is already used by the oauth plugin, and is a general rails convention.</p>
<p>I've left out the users_controller and the parts of the application_controller, since they will need a lot more scrutiny when changed.</p>
<p>This helps make the controller code feel more familiar to new users, and is preparatory work for moving to a standard login system at some point in the future.</p>
