Reducing Unprioritized Bugs

This Greasemonkey script, Check Priority, will check whether you are modifying a bug assigned to you and leaving its priority at "P5 - None". It will pop up a confirmation box to remind you to set a real priority.
Thanks to Milan Vančura for showing us how b.n.c can be improved (check out also the local time script) and for even implementing this one as I stood behind his back!
