Bandmaster V hacking

I improved the antenna status widget to also change antennas for bands. The protocol for this device has not been published, so I had to snoop on the RS-232 traffic to find out how to talk to it.

In addition to performing automatic antenna switching for my tower (40 m – 6 m), it now can switch between four receive antennas for 160 m – 60m. You probably guessed that these are four BOGs oriented NE, SW, NW, SE.

The previously described ft8cmp code and the bandmaster code are now both on github.com:
