-Added anim_attachment_head

--Shared update across most of my playermodels--

-Adjusted eye attachment position

-Adjusted phong shading values

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

-lowered crouch height
-adjusted weapon placement

-moved the model backwards

-Scaled up the model
-lots of animation improvements
-animation smoothing added between movement and stopping
-ragdoll physics improved
-added custom ambient occlusion to the texture
