// @namespace      tag:brainonfire.net,2007-01-13:disemvowelwordpress
// @description    Add a "Disemvowel" button to the comment moderation screen in WordPress. This removes the vowels from the comment text (and escapes any HTML), adds "Disemvoweled troll: " to the beginning of the commenter's name, and changes the commenter's homepage link to the URL of the Wikipedia article on disemvoweling.

//This stays in scope because of the disemvowelOnce closure kept by the button event handler.
