Parametric modelling dialog layout is rearranged to accommodate longer labels automatically generated for Input Functions.

RoiStats4D dialog:  when TAC for the ROI is obtained, its label is automatically formed consisting of the Roi Name + ROI size in mm3.  This allows user to avoid manual typing in when importing the Input Function inside the Parametric Modelling dialog.

Dialog Roi Stats4D:  Added the "Show Median"  checkbox (as apposed to "Show Average") .  Roi TAC is shown either in Median or Average mode. Same choice for Saving and copying it to the Clipboard.
