    Replace plNearestPoints with a deticated solution

    Implement a dedicated collision detection function (was previously
    relying on Bullet's generic `plNearestPoints`).
    This function computes all the collision data to be used for response:
    coordinates, distance, direction vector.

    This new function has three advantages:

    * Remove a dependency from cloth simulation (Bullet).
    * Give more pleasing collision results (this function is tailored
    specifically for our collision response method).
    * Much faster computation (not benchmarked extensively, but observed
    overal simulation time was cut roughly in half with "collision-heavy"
    simulations).
