Made the soft keying CW wave shaper a CMake option (off by

Browse Source 
default).

Reorganized Modulator interface so that it can control the stream
it writes to.

Make sure only QAudioOutput::stop is called at the end of sending
rather than QAudioOutput::reset which discards pending samples.

Added a quick close option to the Modulator::stop slot to discard
pending buffers if required.

Fix issue in CW synthesizer that was causing CW to be inverted
occasionally.

Made global arrays of symbols volatile because compiler waa
optimizing away reads in sound thread. These global variables
must go eventually as they are a multi-threading hazard.

Simplified TX sequencing to remove some duplicate signals.

Increased range of TX attenuator from 10dB to 30dB. This is mainly for
non-Windows platforms where the attenuator isn't linearized correctly.
