[Equipment] Gaia's Sentinel uses wrong gun model

====================
Type: Equipment
Bug: Gaia's Sentinel uses wrong gun model
====================

Gaia's Sentinel, which is the class 6 Gaian plasma gun, has the multi-barrelled gun model typically reserved for fast firing guns. Its class 8 equivalent, Angel, has the thick single barrel one, which I believe should be shared by both guns.

Picture for reference, with Angels mounted on the back fins.

Changed the model to match the Angel.
