add cas support with a few tests
allow disabling of local logins.  In the instance where an .edu is using cas they may not want a user to be able to log in once the users credentials have been revoked in the system that feeds the CAS authentication server.  This is very optional

FIX: You can't change a subject whilst Flagging

Meta: [You can't change a subject whilst Flagging](http://meta.discourse.org/t/you-can-t-change-a-subject-whilst-flagging/6887)

This revert a change made by @eviltrout in b794830a259d0c76bf804227ab2653b4f9118eb6 in the `flag_view.js`.
The `Em.run.schedule('afterRender', function() {...})` is apparently not enough. Had to schedule the event on the next run loop.

Hopefully, the PR emberjs/ember.js#1235 will soon be merged in and we'll have a proper radio button control in Ember.js.
