Hopefully improve naive detection of high-resolution detectors for peak fitting.

Previously HPGe was differentiated from scintillator based system base purely on number of channels; this failed for some HPGe that had smaller energy ranges or channels had been truncated.  Slightly improved this to now also consider energy range for these cases.  further obvious improvements are possible for the future.
Also a few icon/version related cleanups.
