1. Fix a longstanding (and evidently latent) bug in widegraph.cpp. 

2. Add basic proof-of-concept code that uses QAudioInput instead of
PortAudio for sound input.  By default, this test code is not active,
and it compiles using PortAudio.  To compile using QAudio, uncomment
the line

#DEFINES += QAUDIO_INPUT

in wsjtx.pro.  Note that device selection in the QAudio code is presently
hard-wired to use the default input device.  You can change this 
choice on line 267 in soundin.cpp.
