Allow specifying the TiVo name on the command line (unfinished). Also,
the option to include a port when specifying the address on the command
line looks like it's been broken since 0.2. It should work now.
Completed: Allow specifying a TiVo on the command line (-b), or scan and
connect to the first found (-f).
On second thought, just incorporate the name/TSN lookup into the regular
address handling, instead of requiring "-b". Also, needed a couple more
checks of Zeroconf status.
Skip proxies when autoconnecting.
Updated for 0.5.
