Title: Do not require ClientMissionCleanup to exist

Lukas Joergensen [noticed](http://www.garagegames.com/community/forums/viewthread/134056/1#comment-844077) that ParticleEmitter requires a SimGroup called ClientMissionCleanup to be present or it will have a tantrum. This seems like bad practise.
