Added UDP discovery to RFSpace.  Working but not integrated with UI yet
Integrated RFSpace discovery into options and Initialize.  Couple of related bug fixes
Big Bug:  I forgot to move all the audio input stuff from SDR to DeviceInterfaceBase, so none of the devices that use sound cards worked.  Moved all the audio to PebbleLib and removed from Qt.
For reference only.  Checking in all the audio changes that were made and moved to PebbleLib.  Checking in here just so we have Git continuity.  Will delete all the files next
Removing files that were moved to PebbleLib
Update devices that use audio input to call DeviceInterfaceBase::Initialize, Start, Stop to handle audio input
