// ChangeLog
// 2006-??-?? - 0.3 - take over the normal edit button instead of using a custom link
// 2006-03-12 - 0.2 - Fixed the code for encoding the form data that was corrupted by GM downloading it which I'd never known before
//                    which means my quick reply script has been broken for months and I never knew.
// 2006-03-12 - 0.1 - Initial release
