some changes related to buffer for gshaderrrrr

fixed borken icons

added some stencil fix for gshader fix

- Added "Draw Projected Lights on Viewmodel" experimental option. This should make viewmodels look better under projected lights, and work with Real CSM
- Added TTK display in damage screen
- Grenade fuse timer now properly subtracts time spent throwing
- Breath meter cost per shooting is now normalized by RPM
- Fix some issues with Physical Bullets
- Improve attachment toggling
- Improve stat caching behavior to hopefully reduce stuttering

Fix penetration causing shotguns to do inconsistent damage
Other internal changes

no melee on bipods
blur no longer runs if gmod is unfocused (makes my computer quieter)
Do not freak out on negative DispersionSpread values
Add SWEP.NoCrosshairShootTimeGap

fix no distant and explosion sounds when running 1 player server

• Localization changes: MuzzleVelocity and EntityMuzzleVelocity are not real stats and have been completely removed (use ShootEntForce instead)
  
• Use PLAYER:IsSprinting() to check if player is sprinting in addition to existing checks, to support addons that call PLAYER:DisableSprint() etc.
  
• Implement SWEP:CustomAmmoDisplay() to show bottomless clip properly on custom HUDs like D/GL4
  
• Adjust stat cache to not cache beyond the same tick. This was causing issues on move/recoil related stats that update very frequently.
  
• Move-related stats now only consider horizontal velocity. This prevents jumping from bouncing your crosshair due to SpreadMove, notably.
  
• Improved melee lunging and backstab behavior.
  
• Aim assist won't lock onto NPCs considered allied by IsFriendEntityName. Notably, this fails on hostile rebels, but idc.

another fix for timers, sorry

fix timers broked

Advanced camo now applied to individual models, not once per texture. allows coloring multiple same attachments or ones that use same texture, like handguards
Toggleable/advanced camo atts now save more reliably
Shoot and explosions sounds now can be heard on whole map in multiplayer (for explosions this requires update for each weapon pack :/)
More up to date chinese loc by WhatUziname7
Secret arc9_vm_adsstyle console command
Reverted change that made some scope reticles look incorrect
Variable zoom scopes don't get reset each time some attachment gets toggled
Converted ogg files to wav in base to reduce stutters
Fixed randomly missing trigger sounds in multiplayer

Changes about customization menu:
- rotation is smoothed now
- dragging with middle mouse button rotates gun in another axis
- mouse4/5 buttons now act like page up/down in browser - goes back and forward through selected attachment and folders
- pressing e while hovering attachment now toggles it or changes its camo slot (shift+e to change toggle in opposite direction)
