Fix polygon merging. Add polygon:scale(s, cx, cy).

Polygon merging failed due to invalid computation of shared edge.
polygon:scale(s,cx,cy) scales polygon by factor s wrt point cx,cy.

Collision detection using GJK/EPA instead of SAT.
...
The Gilbert–Johnson–Keerthi collision detection algorithm is
significantly faster than collision detection using the separating axis
theorem. GJK can only determine whether two shapes collide, but not the
penetration vector. The expanding polytype algorithm can use information
from GJK to quickly find the required vector.

Fix issue #10 . Fix spatialhash drawing.
...
Shapes were not inserted into the spatial hash when not moved. Shapes
set to passive directly after creation would not be in the hash,
resulting in no collision reports.
Spatialhash drawing updated to the new cell indexing method.

Fix triangulation. Use class-commons. Add hash:draw()
...
Polygon triangulation bug:
In some cases Kongs triangulation algorithm produces triangles
with collinear points. The Polygon constructor removes one of
these and throws an error because there are not enough vertices.
Checking if the current points in a triangulation step are
collinear and discarding those triangles fixes the problem.
Class-commons lets you use any supporting class system as
backend for HC.
Add SpatialHash:draw() for debug purposes.
