Remove all FB events

/**
 * This is a quick and straightforward utility that attempts to
 * purge all Facebook events from your The Events Calendar installation.
 *
 * Before use, please backup your database and ensure you know how to
 * restore that backup!
 *
 * Easiest usage is to copy and paste in to your theme's functions.php
 * file, then login and view the list of events: you may need to refresh
 * the page a couple of times or more but you should ultimately find
 * that FB-related events are dropped altogether. With that done, PLEASE
 * DELETE THIS CODE - especially if you intend to start importing more
 * FB events!
 *
 * (This is provided as a convenience, use at your own risk!)
