Put a looplimit on icom_get_ant_count trying to get autodetect to work
Changes to icom_get_ant_count to try and get this working
Added dummy antenna # args to rigs that don't care i.e. only have 1 antenna
Change to ic785x.c to get antenna calls working
Added automatic detection of # of antennas for Icom rigs
Note that rig_get_ant returns a zero-based antenna# and not RIG_ANT1/2/3/4....
rig_set_ant on the other hand takes RIG_ANT1/2/3/4 as the argument for antenna
These RIG_ANT settings are a bit mask
This may have to be converted in the rig back end to whatever the rig expects
