Gas Detector that is more responsive than smelling, can detect odorless gases, and can even detect gas when wearing a gas mask

Optimized particle effects will have their particles cleared when they are cleared, but when they fade away, their particles will remain

Added a breathing noise the GChem Gas Mask
Optimized Gas particles, when cleared, will have their particle effect deleted too

Added an overlay to the GChem Gas Mask, wish to add a breathing sound but am facing technical difficulties, disable the overlay with the variable in the GChem config GasMaskDrawOverlay.
Added a flag for a gauze respirator, similar to those used at the 2nd battle of ypres, that half protects against just chlorine gas. No entity exists to enable the flag by default though, primarily designed for the Boondocks WW1 server.
Rebalanced the mustard gas evaporation rate so objects are usually hazardous for 5 minutes and can be smelled for 10 minutes on average, also added the variables ContaminationEvaporationEffectMultiplier and ContaminationAbsorptionEffectMultiplier to the GChem config to allow admins to tweak evaporation and absorption rates without creating unreasonably deadly gas

Modified Lethal dose code to make the mod more compatible with gib mods. (so npc's don't explode)

Players dying from gas poisoning won't die after respawn

Changed exposure damage code to allow VJ npcs to be damaged

Previous update didn't work

Added a damaging blast to bursting grenades
