Tremendous work to get first working version of ASIM!

Details:

--Renaming in all for standardization:
  "ACRO / ACRONYM" -> "ASIM"
  "Scint" -> "Photons"
  "Counted" -> "Detected"
  ".adaq" -> ".adaq.root" (enables TBrowser to recognize)
  ".acro" -> ".asim.root" (enables TBrowser to recognize)

--Major overhaul of AAComputation::CalculateASIMSpectrum() and
  AAComputation::LoadASIMFile() to complete first working version of
  the ASIM loading/spectra'ing/analysis. Removed all of the old
  "LS/ES" functionality.

--Overhaul of AAInterface widgets and ::SaveSettings() in compliance
  with above

--Changes to all other files mostly deal with the above changes
