Fixed rumble after Xbox controller initialization 

When we initialize the controller it has an internal rumble sequence number, and if our rumble sequence number doesn't match that, rumble won't happen. To fix that we cycle through the range of sequence numbers, and at some point we'll match up with the controller's sequence number and it'll roll forward until it matches our next rumble sequence number.
