// Gmail Signature Float
// version 0.9 BETA!
// 2007-10-21
// Copyright (c) 2006-2007, Tim Jarrett

//
// --------------------------------------------------------------------
//
// This is a Greasemonkey user script.
//
// To install, you need Greasemonkey: http://greasemonkey.mozdev.org/
// Then restart Firefox and revisit this script.
// Under Tools, there will be a new menu item to "Install User Script".
// Accept the default configuration and install.
//
// IF YOU ARE UPGRADING FROM A PREVIOUS VERSION OF GMAIL SIGNATURE
// FLOAT, go to Tools/Manage User Scripts and manually uninstall the
// previous version before installing this one. Sorry, this is a
// limitation of Greasemonkey.
//
// To uninstall, go to Tools/Manage User Scripts,
// select "Gmail Signature Float", and click Uninstall.
//
// --------------------------------------------------------------------
//
// WHAT IT DOES:
//
// mail.google.com (Gmail):
// - Adds your signature above the quoted text, rather than below it
// - Updates the Settings page text to reflect this change in
// functionality
//
// --------------------------------------------------------------------
//
// PROPS TO:
//
// Robson Braga Araujo (http://www.userscripts.org/people/868) and
// his "Gmail: Random Signature" script. I lifted his method for
// searching through Gmail's functions. I'm not sure if it helped...
// but it is being used in this update.
//
// --------------------------------------------------------------------
//
// CHANGELOG:
// 0.9.2
// - The options "Allow Html", "Remove Dashes", "Exclude from Replies/Forwards" and "Signature // Above Quoted Messages" are functional again
//
// 0.9.1
// - Workaround to make it compatible with new GraseMonkey
//
// 0.9
// - Added option to not include signatures on replies
// - Added option to not include signatures on forwards
//
// 0.8.2
// - Fixed script so that pressing the "Compose" button from the contact list pages
// appropriately allows HTML and clears dashes (thanks for the bug report Raymon)
//
// 0.8.1
// - Fixed 'Settings' to work for other languages
// - Slightly changed way that settings are injected into the DOM to be a bit
// more friendly
//
// 0.8
// - Added ability to turn of Signature Floating
// - Added a link to the UserScripts page for this script for update checking
//
// 0.7.1
// - Fixed bug in function body extracting causing GSF not to work sometimes -
// GSF should now work on Gmail and Gmail Domains
//
// 0.7
// - Did some house cleaning on function names to try to keep them consistent
// - Added option to use HTML in the signature
//
