Minor texture fixes for guard divisions.

Forgot Casual Scientist.

Added classic versions of the Male and female scientists, remade the lightshirt for the male scientist.

Added the Classic vest for All security models, females and males, with division textures included.

Unlike the original mesh, it uses a unified texture sheet so it stays optimized.

Reworked significant portions of the models, added LoDs to them, and added and removed some bodygroups.

Backported Admin Staff to this version and added custom hands based off the gmod hands instead of model hands.

Reverted to previous version due to lacking sourcefiles for some models.

Removed DX7 and DX8 files and thus support.

While DX7 files were useless, DX8 is still supported in gmod but are no longer allowed on the uploading whitelist, this forces my hand to remove these files as much as i really do not want to.

Remade a few textures, also fixed Eli and Barney a little bit.

Re-added logistics and made biological security their own models.
