BulletSim: Add Bullet body and shape to BSPhysObject and rename

    'Body' to 'BSBody' for disambiguation when reading code.
Complete the API2 interface so nearly all methods on bullet
    classes are available to the managed code. The efficient
    single call simulation step is kept in place while all
    other creation/destruction/parameterization can be done
    in the managed code.
