A community fix for the Huo-Long Heater's ring of fire particles, aiming at visual improvements and bug fixes. ALL changes are done through the particle engine, no custom coding needed from Valve.

Changes

- Replaced opaque animated-sprite ring of fire with actual flame particles to match other flame sources
- Added collision detection to the ring of fire so that it does not go through walls and the environment (Note: this is not a rebalance. The hitbox currently collides with walls, but the current particles do not)
- Fixed missing "worldview" particle system
- Moved the floor-glow explosion to only be present in third person / viewing other players. The floorglow in firstperson causes visibility issues when looking through it

This community fix is also available as mod on Gamebanana.
