Superhollow can be flakey

[erich666]

Superhollow can sometimes create little separate objects at the bottom layer unconnected to the rest of the model, caused by internal tunnels. "Delete floating objects" currently does not remove these. The workaround is to use "fill in isolated tunnels", or to just let these separate little chunks print and pay a bit more for them. The real fix to add to the code is to search the whole model again for groups and delete the small groups.

Unlikely to fix any time soon, but at least I've logged it now.
