Addition to Gun Drone and Tri-Cannon animation

[srmalloy]

A thought occurred to me while playing my Arsenal/Trick Arrow Controller -- Assault Rifle throws spent shells in its animations, but neither Gun Drone nor Tri-Cannon do. Would it be possible to get the shell-ejection part of the Full Auto animation from Assault Rifle added to both of these, so it looks as if the shells are falling out of the bottom of the gun platform?
