Mint integration

While this is strictly speaking against the statement of the README:

This library is an extension of cgmath that provides collision detection primitives.

I approve the idea 👍

Actually, I'm not going to strictly follow the way of original library. Situation in gamedev sphere changed a lot, I'm planning to follow the currents.
I hope cgmath will include mint soon and I wish mint be the de-facto standard wrapper for every math lib.

I took a look at this and created a huge mud-pile in my GitHub folder (the mint-integration branch). It will take some time to convert, as collision is a rich interface, but I definitely think it's a good idea. Traits that are needed to implement collision with cgmath should be private, and only basic traits like those from num-traits and mint should be public. It will certainly help reduce the log driver's waltz that most dependent library-writers have to do.

Now that you are using cgmath 0.18, isn't this a one-line fix?
Cargo.toml:

...
[features]
serde = ["serde_crate", "cgmath/serde", "num/serde"]
mint = ["cgmath/mint"] <----
...

Could even add the other cgmath supported features as well (rand,swizzle,unstable)

But this is quite redundant. All this does is to enable the feature in the cgmath crate, something that should already be done in the end-user toml (as long as the versions match).
