Texture updates + Gun Turret bodygroup added

Texture update. Models now sport normal maps and exponent textures for better lighting management. Alt forms for both now sport turrets from the original game (via bodygroups).

Optimus' alt form has been redone with a clean ripped model. Now comes with a mounted gun turret! Nemesis Prime will be updated later.

Updated Prime's hand textures and Nemesis Prime's trailer texture.

Optimus Prime's Alt Textures have been fixed. No more semi-transparency.

Nemesis Prime now has his alt forms. Updated his and Optimus' textures as well.

Optimus (and Nemesis) have been reworked using a clean extracted model. No more chest gaps and intact normals for proper lighting. Bones are properly renamed for IK chains compatibility with the Ragdoll Mover.

Texture and weight fixes.

Major texture updates. Lighting issues fixed. Nemesis Prime added (robot form only, for now).
