Greasemonkey Script: Show all results from a search, even if they would be hidden by your ignored tags

Question

greasemonkey script to make it so no questions are hidden based on their tags when you are searching

I'm currently ignoring the Perl tag because I don't know anything about it, but occasional I want to search for something regarding it anyway, like seeing the highest voted question in that tag. However, because I'm ignoring that tag, a search for [Perl] shows nothing. Therefore if I want to search for something in one of my ignored tags, I have to unignore-it, search, then re-ignore it, which is far too much effort. So I made a script that disables the hiding of ignored tags on search pages.

Please post any and all suggestions, comments, or questions! :D
