- Added more options to the configDialog in order to customize the MultiPeakFit curves.
- Changed the analytical expression used for the Gauss function in order to make it similar to the definition used by Origin. The old Gauss function in QtiPlot was replaced in the non-linear fit dialog by GaussAmp, since this is the name used for it in the built-in fit functions library of Origin.
- The fitting API should be stable and in a nearly final state, please test it if you have time.
