-Added rimlighting for more realistic lighting

--Shared update across most of my playermodels--

Finally fixed the issue of multiplayer footsteps playing both normal and custom ones at the same time on clients

-Adjusted phong shading values

-Improved c_arms
-Finally added a crouch animation (doesn't actually "crouch")
-ragdoll physics improved

Shared update across all of my playermodels:
-Footsteps will no longer keep playing when the player is dead

-slightly improved the way footsteps are handled in multiplayer (your footsteps would play twice at a time in multiplayer. Fixed partially, now your footsteps don't play twice, but you can still hear other players emit footsteps twice)

-sound effects compressed (from .wav to .mp3 files)

-animations transition smoothly now instead of instantly
-improved weightpainting on c_arms
-texture improvements

-added panicked running animations for zeta bots
-death animation does not loop anymore

-added procedural helper bones to c_arms, massively improving the arm rotation around the wrists when using certain weapons.
