Delete all revisions modification

This module is a life saver, so a big thank you to all contributors.

That said I was wondering if I could ask for a feature request. I was thinking it would be really useful to have a link/button in addition to (or even in place of) the "Delete all # revisions" link when your viewing all revisions of a node. A "Delete all unpublished revisions" link/button would be a real time saver when there are a lot of unpublished revisions you don't need anymore since it takes a long time to click on each revision, hit delete, are you sure: delete... for each one.

Also, while it's more clear now that you've added the number to the Delete all link it still seems possible that a person might not realize that deleting all revisions will delete the published node as well. Adding the additional button would help clarify the existing one.

I just thought I'd put this out there. Thanks again.
