movement.go: added support for basic movement packets

you should be able to view other players and jump around together,
although while testing locally one of the clients would always trigger
the "Some irregularities have been found with your connection to the
server, so your game will be closed" speed check for some reason ???

really not sure, might just be my machine

chunking uhhh works ? kind of, not tested for more than a few seconds
before one of the clients disconnects
