Message:

orxonox/trunk: Explosions on Collision (—HACK—)
also made the FastFactory faster, not turning through the GarbageCollector, as it is not necessary. FastFactory also implements a Static Memeber subscriptor-Macro now
last but not least: new Functions in The ParticleEngine, and some revisited
