Eric House 28bfa3c904 make forceChannel part of CurGameInfo rather than comms, since Android
needs to save it there on receipt of an invitation (doesn't create
full game with comms until later.)  Passes discon2 tests and seems to
work on a single Android device. (Haven't tested inviting on Android
yet.)
