Improved histograms, with region of interest selection capability (making the histograms much more manageable in size)
Added hitfinder/peakfinder 8 - aims to estimate appropriate thresholds based solely on specified signal:noise criterion (ie: no ADC threshold, this is estimated automatically).  Like all things automatic, it can go awry, so use at your own risk.
Added missing mutexes from the free-lock-condition trap (cause of stalling??)
Added support for CspadV1 (reverted in the middle of an experiment)
