Added aabb_circle_collide routine, modify aabb_point_collide
...
If circle center within aabb, calls aabb_point collide. Then, adds to the msv the difference between the closest point on the aabb to the circle and the closest point on circle to closest point on the aabb.
It failed when the circle center was exactly on the aabb edges, so COLLIDE_EPS was added to the apo_normal in aabb_point_collide to force the point off the edge. As such, the "nudge" section was removed. This should definitely be reviewed.

Added aabb_circle_overlap
...
When the distance between the circle's center and the closest point on the aabb is less than the circle radius, returns true.

Added helper function for aabb_circle routines
...
Clamps point coords to the dimensions of an aabb to get the nearest point on the aabb. Returns two integers to avoid garbage.
