[Plugin: revision delete!] Revision Delete!

Nice work on the plugin. Simple steps for the English folks out there:
1/ once you activate the plugin, find and click on “revision delete!” below Settings
2/ type in the number of days if your default is something other than 7.
3/ use the check box if you want to keep the last revision.
4/ click the “Update revision delete!” button.
5/ click “Reset” (it’s more of an “Apply” button)
6/ you must visit each post to apply Revision Delete! ’s magic.
7/ no need to update the post.
