Track ack'd and unack'd packets. When there are ten more of the latter,
skip the UDP-send step. This is probably not the algorithm I'll settle
on (an explicit PING to the relay over UDP might be simpler), but it's
simple and easy.
Send each packet via UDP if that's thought to be working (always is,
now) and start a 10-second timer. If it hasn't been ack'd by then,
resend via Web API. Tested by configuring to use a UDP socket that the
relay isn't listening on. Only problem is that the backoff timers are
broken: never stops sending every few seconds.
The plan's to use the native relay protocol first, then to fall back to
the slower but more reliable (esp. on paranoid/block-everything wifi
networks) webAPI. This is the name change without behavior
change (except that the native kill() to report deleted games is gone.)
When grouping to allow multiple packets per outbound API call I forgot
that some are there to mark the end-of-queue: can't be sent! Trying
caused a NPE. Now if any EOQ is found in the queue that batch is dropped
and the thread's exited.
Making the right_side elem match its parent height prevents the
lower-right region of game list items from falling through and
triggering a toggle-selection event.

As expected, moves are no longer received instantly because the UDP
socket isn't available for the relay to write too once the URL
handler (relay.py) finishes.
Ideally the comms module wouldn't go through its connecting routine in
order to join a game. To that end I added a join() method to relay.py
and code to call it. Joins happen (pairing games, starting new ones,
etc.), but after that communication doesn't. First part of fixing that
would be to make cookieID persistent and transmit it back with the rest
of what join sends (since it's used by all the messages currently sent
in a connected state), but I suspect there's more to be done, and even
that requires a fair number of changes on the relay side. So all that's
wrapped in #ifdef RELAY_VIA_HTTP (and turned off.)
