point_in_polygon() 2.0

version 2.0
- completely different method
- simpler/shorter/more accurate

100% accurate(untill proven otherwise)
detects if a point is within a polygon by using the even/odd intersections rule
even works with concave polygons
doesnt work with polygons that overlap themselves

hover the cursor inside or outside the object to test it.

feel free to change around the points and let me know if any bugs
