* Speed up spectrogram painting by releasing mutex in FFTDataServer
while calculating data prior to writing it, and by adding whole-column
value query methods to FFT objects
* Add paint cache to Thumbwheel -- repaints of this widget were slowing
down the whole spectrogram repaint
* More uses of MutexLocker (named and with debug) and more profile
points
* Make startup much quicker some of the time, with OSC server in place
