Improved Diamond Armor of Fending

If something doesn't work, kick me in the shins and tell me what is it and I'll look into it.

A small texture overhaul of the Diamond Armor of Fending to improve shaders and texturework.

Some spots probably still need some work, but so far I'm satisfied for release.
