Multiple requests piling up can break accelerometer. #4

If a request comes in while another request is still being processed, then the second request is somewhat broken. It appears at the correct time, but the accelerometer is not available to input information.

Probably a good idea to get a more solid system to handle multiple incoming messages rather than relying on it just working.

I believe we just need to make sure we ALWAYS register and deregister on view appear and view disappear. We were doing it that way sometimes but also when the view was loaded, which would/could cause problems

Reopening this until we get a chance to test. If this works then maybe we don't need any other kind of system to handle this, they will just naturally queue( not actually a queue, note) up and be handled one after another.

note: just so this is documented, as far as I can tell the pebble appmsg system does NOT queue messages, but rather it simply lets them fail. For this reason, in the on_msg_dropped method inside app_msg_handler, we retry the send until it succeeds. This gives the illusion of queueing, when in reality its just blocking at the sender until the receiver is ready for it.
