Updates the Particle System, even if the the Particle Systems inherits from DrawableGameComponent.
Updating the Particle System involves executing the Particle System Events, updating all Active Particles according to the Particle Events, and adding new Particles according to the Emitter settings.
NOTE: If inheriting from DrawableGameComponent and this is called, the Particle System will be updated twice per frame; once when it is called here, and again when automatically called by the Game object. If not inheriting from DrawableGameComponent, this acts the same as calling Update().
