Redesigns the Shotgunner variant of the Medic to look a bit different, so he isn't using the same model as the m4 medic. Also since it's just a .model edit it should work with medic retextures. (hopefully)

This is my first overhaul to an enemy with the new GLTF model tool. Super easy to edit models with.

Extract into mod_overrides.

Might do the other medics in the other factions some other time...
