Added the ability for osgParticle::ParticleEffect to switch off the automatic setup.

Normally the automatic setup is useful, but in the case of the .osg support this automatic
update was forcing premature loading of imagery that wasn't necessarily, and can lead to
reports of looking for files that arn't present.
