Dramatic collision changes (.. improvements)
Dramatic collision changes (.. improvements)

So, I don't think I was really doing AABB collision detection before.

I also am adding at least half of a more-broken, weirder system here,
and I'll likely pull it completely back out some day. That's the huge
function with the interval calculations. But the new AABB function is
actually good -- it's cobbled from a few blogposts I found 2-3 months
ago, but things finally really started working when I began using it.
