Fixes Not compiling on rustc 0.12.0-pre-nightly #8
Fix `non_snake_case` related warnings.
Add convex MinkwskiSum implementation for Polyline and TriMesh.
Completely remove the concept of `margin`.

This is an optimization for physics simulation that is hard to explain at the geometric level.
Those margin can still be emulated by the user using a greater `prediction` threshold, and
adjusting the penetration depth informations after their collection.
Make the `ConcaveGeom` vs. `Geom` detectors aware of the prediction system.
Implement ToPolyline for Cone, Capsule and Cylinder.

Also fix the ToPolyline implementation for Cuboid.
Implement `RayCast` for the `BoundingSphere`.
Rename `BVT::new_kdtree` to `BVT::new_balanced`.

This did **not** build a kdtree.
Update to tha last rust-nightly.

Version of rustc: 0.12.0-pre-nightly (a1f497309 2014-09-09 23:55:43 +0000).
Add a `::new()` constructor for `NoIdDispatcher`.
Move the `data` module as a submodule of `utils`.
Fix the initialization of the 2D convex hull.

Sometimes, the first vertex of the input array was ignored.
Switch the normal and uvs index slot for the `SplitIndexBuffer`.
Replace `n-dimensional` by `2 and 3-dimensional`.

Higher dimensions (except 4) are not very useful/tested.
Update to the last rust-nightly.

Version of rustc: 0.12.0-pre-nightly (79a5448f4 2014-09-13 20:36:02 +0000).
