Log Message:
-----------
Small particles feature: Multiple group visualization counts per group object are now possible (+/- buttons next to the count list). This allows for example an array of duplicated objects "ob1, ob2, ob1, ob3" without duplicating the actual object (ob1 in the example) in the group.
