[GSAS-II] Synchrotron parameter file

[Bartłomiej Gędziorowski]

Yes,

I know it sounds crazy, but if someone chose by mistake a wrong set than 
it would be nice to have the possibility to easily correct mistake. I 
think it would be easy to implement it by adding to the menu a position 
and use the same dialog window used during adding a histogram.
