Dialog EdgeWaveLive: fixed the defect when changing one of the "Live parameters" would add an additional mask layer without deleting the present layer first.

Breast lesion workflow:  corrected the defect in   PET->T1 registration when the SI volume has to be specifically Active resulting in the warning message.  Now any layer can be active before the operation.

CERENE3D workflow Menu:  added "T1: Segment Kidney  {BLANKET,CONSTR}" items. 
Added a place holder for the automatic kidney seed detection.
