[Particles] Check for intersection with any worldobject after X ms of movement

[mrzzzrm]

Currently the explosion particles of a rocket fly throught the hit object.

Solve by

1. Calculate Sphere of all Particles after X ms (initial radius + maxspeed * X)
2. WorldTreeQuery all WorldObjects in Sphere
3. Check Projection of Particles after X ms against these WOs

just an idea: why not check later instead of projecting? this would avoid a (further) performance drop in the exact moment the bullet hits, which already exists because of split detection et cetera

[xchrdw]

the advantage of the current solution is that many particles never get spawned -> No buffer slot needs to be found and less communication with the gpu needs to happen.

can somebody else take care of this? I'm full of tasks right now ;)
