/*
This is a port of Stuart Langridge's Nice Titles to Greasemonkey.
See http://www.kryogenix.org/code/browser/nicetitle/ for the original
The main differences between this and the original are
1. Removed the browser detection code - we are always in Firefox
2. Added a 1/2 second delay to the display of the title. I think it's nicer that way.
