//
// 26 April 2006
// - Fix finding username in new gmail layout
// 22 March 2006
// - Only add newline if we have both parts of the signature.
// 09 March 2006
// - Workaround for bug in Firefox 1.5.0.1. A break inside the for caused
// Firefox to crash.
// - New Gmail layout may put the username in a different tag.
// - Make it faster when loading Gmail.
// 23 January 2006
// - Updated to work with new version of Gmail.
// 09 December 2005
// - Updated to work with new Greasemonkey for Firefox 1.5.
// 15 September 2005
// - Make the configuration per username, so that everybody can have their own
// signature and taglines.
// - TODO: Store configuration on server.
// 13 September 2005
// - No ugly editing anymore. The script adds a box to your preferences so you
// can edit your taglines and signature.
// 12 September 2005
// - Removed lots of unnecessary stuff.
// - Corrected a bug where the sig wouldn't change if you clicked in
// "Compose Mail".
// 11 September 2005
// - First Release: must edit the tagline array in the script.
