/* NOTE TO USERS OF VERSION 0.0.1:
* Sorry for erasing any modifications you made to the filter settings.
*
* I didn't put much thought into version 0.0.1 and, as a result, it was
* impossible to release an update without erasing modifications.
*
* I'm now storing settings via GM_setValue, so it should never happen again
* and there's a proper configuration GUI available at
* Greasemonkey > User Script Commands... > Configure Result Filter...
