Have Dip switches and cheats be set by host only

[Prinygod]

Only host should be able to set switches and cheats, to prevent desyncing, and when the host does all peers should automatically duplicate. (again to prevent desyncing) Finally peers who connect should also copy the host, ideally switching back to their preferred Dip switches once they leave the game.

Dip syncing has been added, but cheat syncing hasn't so ill leave this open
