-Added rimlighting for more realistic lighting

-Added more sound effects

--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

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

-added a few sound effects

-fixed one bone rotating the wrong way while ragdoll

-smoothed out animation transitions
-improved c_arms

now uses player_bird_ commands instead of player_griffin_

-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 still emit footsteps twice)
