Script Summary: Make your own google-scholar searches persistent. For scholar.google.de only (the german-language site).
Added different type of event handler registration (via listeners), fixed minor typos. Now it works again...for me, at least (ff 2.0)!
This is a derivative work of the original version from 2005, created by at least two(?) predecessor authors.
The previous version http://userscripts.org/scripts/show/836 was defunct.
Note: Seems to work on scholar.google.de only (the german-language site), not the .com site
