Simple, lightweight, general purpose collision detection

[vrld]

Good news, everyone! HardonCollider now has a new, leaner, simpler, better API!

Callbacks are gone, groups are gone, ghost shapes are gone. What is left is immediate mode collision detection (similar to bump.lua): You decide when, where, and what you want to check for collisions.

To commemorate the change, HardonCollider is now called HC. On top of that, the documentation moved to ReadTheDocs.org: http://hc.readthedocs.org/en/latest/

Speaking of the devil! Congrats on the new release!
