Remove `"flammable" "no"` from 2 PHX bombs
`"flammable" "no"` did nothing before, but does a thing now, and apparently these props have had them the whole time.
Added MainEyePos, MainEyeAngles, use it for properties.lua
These 2 functions store main view's position and angle without being affected by any other view or render.RenderView
Fixes properties not being usable if render.RenderView is called at all times
Fixed render.RenderView affecting FOV for worldclicker
Fixed sun glow overlay not rendering in water
Minor viewrender changes from CS:GO
* Clamp fog lerp, restore position/angles for reflection/refraction views after rendering
Minor optimization for DecalTermAtPos
Fixed (near?) infinite loops in EnumerateElementsInBox
* This was caused by having mins be bigger than maxs, or negative radius for EnumerateElementsInSphere
