Add ability to do additional collision queries

[LeXXik]

We already have following queries for linear casts:

• [x] cast ray
• [x] cast shape

We should also add:

• [x] 'collide point' - test if a point is inside some shapes
• [x] 'collide shape' - test if a shape is intersecting some shapes

This is fixed with #37 and #38
