When multiple jobs of the same kind are listed, visually group them.
While this doesn't actively group them (i.e. having a copy, a move, and a copy again won't move the second copy job to the first - there's no real model underneath, so we cannot just drop a sort proxy model ontop), it still improves the most likely situation of copying multiple different things at once.

As per VDG request

Started two copy progresses, only got one heading. Verified that when I quit the first job, the title of the second would show up (binding magic)
