[aprssig] Rotor control

I just tried it on my Rotor-EZ.

AP1080<CR> will rotate the antenna to 80 degrees.

AP1090; will store 90 degrees in the Rotor-EZ memory.

AM1; will rotate the antenna to the value stored with the AP1XXX; command.

AM1; is NOT needed after AP1xxx<CR>

Note the the AP and AM must be upper case.
