Add inertia vector

[tul1]

Hi,
Somebody knows how to pass an inertia vector to the ColliderData create method? I'm working in the dev branch.

The following way doesn't compile.

auto boxColliderData = bullet::ColliderData::create(
BOX_MASS,
bullet::BoxShape::create(BOX_SIZE, BOX_SIZE, BOX_SIZE),
BOX_RESTITUTION,
BOX_FRICTION,
BOX_ROLLING_FRICTION,
math::vec3(0,0,0)
);

The port to the new math API (using GLM) on the dev branch has been poorly done on the ColliderData::create() method. It expects a math::vec3* instead of a math::vec3.

Fix + pull request are welcome!
