Message:

add new configuration item: PDF_Rmax maximum radius for G(r) calculations; rarely changed by user
Change PDF GUI Rmax to be for the max r for G(r) plot - no longer r max for calculation
This speeds up optimization
Fix problems with PDF peak table - principally the rowlabels needed to be str not int - crashed wx 4.0 & gave bizarre effects in wx 3.
