manage a single connection to the relay for all of its games. Works
so far to the extent that the game's playable with all boards on the
same device (with checkins about to come) as long as all boards are
open. (Client doesn't handle opening closed games yet.)
once UDP sockets and/or per-device (not per-game) connections come
along. Lots of changes, most not involving code flow but a couple
that did. So far two gtk games can connect and exchange moves.
Haven't tested reconnection or store-and-forward.
