Re: csisland improvement

Sorry, I wanted to mean that the trajectory of the fast moving arrow
could not be computed through the physics2 plugin (that is using the
Bullet simulation library), but of course some physics simulation should
be done in order to have some ballistic effect.

The current motion of the arrow is controlled by the animation and has
been defined by the artist. This should be changed and the arrow should
be separated from the crossbow once it is shot, then its trajectory
would be computed eg through the same code than the physical particle
effector.
