Flatten Group

As in, ungroup all objects inside a group, so that there are no groups inside that group. Probably on a context menu button while any number of groups are selected.

Some creators don't think about the group structure of something they're working on, and you can end up with crazy numbers of nested groups for a simple object. This is wasteful on gameplay > things thermo, especially if the user of the asset wants to clone it around thousands of times.

At the moment, ungrouping all the nested groups can take a long while. And if we've already cloned it around a load before we realised it had this problem, it could need a loooooot of work to make this fix.

For example, a tree with tons of leaf objects and they're all grouped 2 at a time for some reason. Or a ground made up of a patch of 3 patches of 3, each being a group of 2 sculpts overlapping each other.

The advisability of such objects aside... if we could use those things grouped as they are, but then ungroup the whole lot in one button press would be a useful way to work. Or flattening an object we know we don't want to have internal structure would be a good thing to do when we import it in the first place.
