Add Waitlist to Event restrictions

Include the waitlist to these event restrictions. Example: if a person puts themselves on a waitlist for an event at 9:30am, and then puts themselves playing in the next event that starts at 11:00, the restriction should include the waitlist so that they do NOT get autoregistered to the 9:30am event. In addition, if the waitlist could be added to the event window booking that would restrict players from playing back to back
