TIFS/Virtus
- ToolParticle effects added
- HUD added
- Tool-interaction, repair of turrets working
- Began adding possibility of using "global" particle effects. Not sure if it matters to the pipeline, but the particles for the player's should probably be reverted and based on them so that they may be culled later on (if performance issues arise)
- GMParticles replaces all previous variations of the file-names, and some new messages added for registering global particle systems.
- Sphere-Ray intersection check now works correctly, ignoring intersections behind the starting point
