Login: add a spinner for better process indication

Browse Source 
We need to do a better job of indicating login process. This can
sometimes take a few seconds (particularly if you get your password
wrong): we need to give better feedback of what's going on.

This adds a spinner next to the login button if the authorization takes
some time.
