Spawn fresh particles

[wbk]

It would be really helpful if there was a mode in the spawn operator that output 'fresh particles' with no properties or shapes.  For example removing/nulling lots of unneeded custom properties on spawned particles in certain circumstances is overly verbose.

I could see an option like that being useful, sure. I'll add it to the 'inherited properties' rollout of the Spawn operator.
