Added invalidation of the sliced object when gap-fill enabled/disabled if the object is painted using the multi-material painting gizmo.

Browse source 
Filtering of unprintable regions in multi-material segmentation depends on if gap-fill is enabled or not. So sliced object is invalidated when gap-fill was enabled/disabled by option "gap_fill_enabled" or by changing "gap_fill_speed" to force recomputation of the multi-material segmentation.
