   • Allow autoconversion of voice keyer file to selected TX mode's sample rate. (PR #145)

Changes from v1.5:

1. v1.5.3:
   • Simultaneous decode of 2020, 1600 and 700C/D/E (without needing to push Stop first, change the mode and push Start again).
   • Dynamic switching of the current Tx mode between the aforementioned modes, again without needing to restart the session.
   • A Tx level slider on the right hand side of the main screen to fine-tune transmit output (to more easily avoid clipping ALC and conflicting with other soundcard ham radio applications).
2. v1.5.2:
   • Updates storage for sound card configuration to use device names instead of IDs.
   • Detects changes to computer sound card configuration and notifies user when devices go away.
3. v1.5.1:
   • Experimental support for reporting to PSK Reporter added.
   • Bug fixes with audio configuration to allow mono devices to be used along with stereo ones.
   • Tweaks to user interface and record/playback functionality to improve usability.
   • Bug fixes and tweaks to improve voice keyer support.
4. v1.5.0:
   • FreeDV 700E, better performance than 700D on fast fading channels
   • FreeDV 700D/700E clipper to increase average transmit power by 6dB
