ClipperLib: Optimized PointInPolygon() to calculate cross products

Browse source 
with int64s instead of doubles.
Polygon / ExPolygon: contains() reworked to use ClipperLib::PointInPolygon().
	The Slic3r own implementation was not robust.
Fixed test_perimeters after recent refactoring (sorting of extrusions
	into LayerIslands)
