/*
Changelog:
2005-08-27 2.1
* Played around with the encoding. Seems GM 0.5.1 is still a bit buggy.
* Removed the part that made the thread you're viewing turn bold in the thread view.
Lunarstorm already does this for Firefox now.
* Added license block
* Some changes in the HTML on Diskus broke the scripts. Made it work, I think
it's even better now.
* Added xpath-function
2005-06-16 2.0
* Script now remembers which threads you've viewed and not.
2005-06-01 1.0
* Makes the thread you're viewing go bold in the thread view.
