Bulk action to purge revisions

• Introduce a bulk action to purge selected posts' revisions

From https://github.com/ethitter/WP-Revisions-Control/issues/3:

Hi,

I have even more than 10 revisions to one post because I migrated from old Joomla to WordPress with ~450 posts, so it's incredible amount of revisions.

I limited revisions for posts to 4 and for pages 5.

But I would remove those that "overflows" limits. As I saw there are only option to purge all revisions and only for single post/page.

I could do it by SQL in my database, but it would be nice to have option to do it bulk from WordPress. Exactly the same way like Regenerate Thumbnails do - you could go to Tools and regenerate every thumbnail or go to Media Library, choose some images by checkboxs and choose regenerate action from bulk action's dropdown.

Or maybe there are already something like this, but I couldn't find it?

Greetings
