* Add force_login option to OAuth authorize page
For when a user needs to sign into an app from multiple accounts
on the same server
* When logging out from modal header, redirect back after re-login
* Add render_views in more places
* Delegate methods from account to user with allow nil true, so that admin accounts show view renders when missing a user
* Use actual account instances in authorize follow controller spec
* Add failing spec for oauth/authorized_applications controller
* Use explicit reference to flashes partial from admin layout
Because some of the controllers which use the admin layout do not inherit from
application controller, this partial is not in their view path.
