ehouse bdb06cbdf8 Use a single general-purpose callback passed into palm_bt_doWork where 
it's needed, removing those passed into _init and _send.  When client
is unable to connect to host, raise alert to user and give choice to
continue trying.  Clear 'suspendBT' flag when user manually resends or
opens different game.  Currently this happens only on guest's failure
to find registered SDP; should also extend to remote device not
running at all and to host failure to send to guest.
