Reset MaxArmor on player spawn (unless during level transition)
Do not render $no_draw materials on models in depth pass
Fixed a crash with game.MountGMA
Fixed armor being stripped with hl2_episodic on level change
Make player model Alyx use separate head material
* Fixes Alyx NPC losing phong detail in the head material
Minor changes to viewpostproces from TF2 SDK
* Removes duplicate creation of mat_colorcorrection
Delete serverside mat_hdr_tonemapscale & some related entity IO
* Removes SetTonemapScale and BlendTonemapScale hammer inputs from env_tonemap_controller. These 2 inputs never actually functioned, especially in multiplayer, since they set mat_hdr_tonemapscale which is never read anywhere, and is reset every frame.
Adjust texture panel header to scale with screen width
Added Entity:PlayFootstepSound
* Also fixed NPC footsteps not using leg positions for trace start location, so now the footsteps should be more accurate to the surface under each foot
* Also fixed NPC footsteps not respecting intended footstep sound volume
