Minor hotfix to fix console errors (vmt EOF related).

RNG version was upgraded to SYS RNG, allowing for both RNG & the ability to select/lock skins. (Require's Ellie's SYS RNG core mod)
Skin changing/randomizing in situations where it shouldn't have been amended.
5th skin has been enabled by default, with the glowing tattoos removed. (Black-sclera eyes have not been enabled, however)
Minor adjustment to the face; Francis should have his lips properly closed at the front now.

Added "$nodecal 1" to all materials to alleviate index buffer crashes.
Adjusted first-person arms to reduce arms obscuring vision with certain weapons/FOVs.
Restored missing alpha channel on normal maps.
