Enhancement: Recursively remove Empty folders

[sahil48]

It would be really useful to add a button to bookmarkdupes to keep deleting empty folders until no empty folders are left. That way, if there are 4 empty folders nested in one another (ex. folder 1 (empty) > folder 2 (empty) > folder 3 (empty) > folder 4 empty, folder 1 (empty) > folder 2 (empty) & folder 3 (empty) > folder 4 (empty)), all 4 folders would be deleted.

I had already thought about it, but it would be quite confusing for the user, because the "Empty folders" button would then actually display non-empty folders. Also, unless the presentation is in a tree form, the marking would be quite confusing (because non-empty folders would have to force selection of their children).

One might perhaps think up a corresponding user interface, but at the end of the day I think that this is not worth the hassle: In the worst case, the user has to repeat the procedure

1. Press "Empty folders"
2. Mark all (or whatever he wants)
3. Remove selected

as often as what is depth of the deepest empty folder which is typically not more than 3-5.
This inconvenience is probably less than the inconvenience by a more complicated interface.
