ehouse a07a5f2822 cleanup; replace a bunch of EvtAddEventToQueue calls with 
postEmptyEvent; pass transport type with incoming packets so they can
be rejected if not on expected channel (to stop IR, which is always
on, from injecting into a BT game); do BT work and fire timers even
when menu is down; don't let robot run until after board is drawn for
the first time; on startup, don't let robot run until after board is
drawn once.  Up version to b3.
