Inferior copy of Mediamatic plugin

This seems to be an exact ripoff of the Mediamatic Media Library Folders plugin. I didn’t look at the code but I assume it was copied wholesale. As far as I can tell, the only difference is the introduction of a serious bug, to wit: the subfolders feature doesn’t work at all. You can drag to create a subfolder, but when you leave the screen and come back, the subfolder has reverted to a top-level folder.

In addition, it has the same bugs I recently reported for Mediamatic.
