• Make all ACE Interaction Names use sys_core_fnc_getDescriptiveName in favour of format ["%1 Chn: %2", _radioName, api_fnc_getRadioChannel].
  I noticed yesterday that the GSA action to connect a PRC-77 displayed the radio's frequency as [MHzKnobPos, KHzKnobPos], since api_fnc_getRadioChannel returns that raw data in its case. getDescriptiveName's return is IMO better in all situations, as it will properly format channel data for all radios and also display useful info like the PTT number.
• Improve the PRC-343 description to show Bk x Ch y instead of the absolute (overflowing) channel number.
• Improve the SEM52SL description (and switchChannelFast hint) to show H and P channels as letters instead of numbers.
• Improve the SEM70 (and SEM90 Rack) description to show x MHz in HW mode and Chn x NetID y in AKW mode.
• Always pad out the decimal positions of frequency-based radios, i.e: 30.00 MHz for the PRC-77 and 30.000 MHz for the SEM 70 (in HW mode).
