Add external_register_url to link to external registration site, hide password form if enable_password is false

Our users have problems with the disabled register button and
keep creating tickets. Add option to link to external site instead
of a disabled button.

People get confused by the login form if they should only
use the oauth login.
Now the login form is hidden if enable_password is false.
It can be shown by clicking the welcome text, in case an
admin needs access
