Project::OSiRiON

Allow a player to control (some) weapons on another player's ship,
making him a gunman

The details of this idea still need to be worked out.

Improved particle systems: weapon effects, engine effects, explosions, smoke...

An improved framework for particle systems unifying all of the above.

DONE
- Particle system code needs to support multiple ejectors per system,
at the moment a particle system is created for each ejector
- Add fine-grained control parameters (alpha start mid end) (radius start mid end) ..
See tremulous particles
- Streak style particles (aka 'trail sprites')
- replace [ejector] with [sprites] [flares] [trail] etc
- ejector thrust trigger
- ejector impulse trigger
- ejector explosion trigger

TODO
- Flame style particles -> needs thinking, how to do it exactly
