ScrollList gadget fix

When 'select only one' or 'multiple selections forbidden' is in use any selection changes first deselect all.
However, in the second case, the module overrode the caller's selection reason so adjust clicking on an item would not deselect it - instead reselecting it!
Logic ammended.
