Uses wp_cron to delete comments each day that are marked "spam" in the database.
wp_commentstable after spam is deleted. Updated DB call to allow for alternate wordpress table prefix.
add_actionwas added to the "Delete Spam Daily" button so it would actually delete spam once a day. :-) In addition to a "Stop Deleting Spam" button, a button was added that reschedules the cron to happen in 1 minute so you can be sure your crons are working right away.
