Login dialog

If the attempt to get the license ('/api/v1/config') or user info ('/api/v1/me') fails, force user back to the login page. Additionally, call Authorization.logout() to make sure any residual token or user info is cleared.

Tweaked the login HTML so that ng-show on the login dialog header message will cause the message to show when the sessionExpired variable is null or undefined.
