[Events +] Registration Redirect

When new users click "I'm Attending" they are taken into a login/registration process that ends with a thank you page. It would be better for all if that process looped the user back to the event page so they could click "I'm Attending" again (or have it know that they clicked it in the first place). As it stands, the user does not get RSVP'd, and it just leaves them on another page with no links or redirects back to the event.

Another, maybe even better, solution would be a popup/modal for login/registration so they don't actually leave the event page.
