Fix random crashes in ArchiveCollector

This was a hard one, actually. Since we only returned a pointer from the
ArchiveCollector, it worked _most_ of the time, but crashed at random
when the view was reading the tree while the collector was updating it.

So create a working copy constructor for SmRootItem and return a copy of
the the tree when the collector is done.

I bet that's also the reason for the random crashes in the filesystem
view.
