PixelPaint: Make "Crop Image to Selection" work with disjoint layers

Browse source 
The "Crop Image to Selection" action will now crop all layers within
the current selection.

Any layers outside of the current selection are deleted.

If there are no layers within the current selection, a new layer the
same size as the selection is created, which has the same name as the
current active layer.
