Title: Redirect velruse logins back to the page where login was performed

After logging in with Facebook(velruse), the user is redirected to the page she came from.
Velruse can not redirect to custom URIs when used as a service and can then only be used with POST,
so adhocracy first remembers the users current URI, redirects her to a page where a login form is automatically send and then redirects her back to the URI where the login was performed.
