Google Auto Pager 2008

Description:

This is a fixed version of Pawel Kubisz's adaptation of ma.la's (?) Google Auto Pager script.
When you scroll to the end of a page of Google search results, it will automatically pull the next results in and auto-load them.
The script is always-on. The previous version was activated by double-clicking the page. If you prefer this, change two lines of code near the end. (The lines are marked by a comment.)
Note that I didn't do most of the hard work here, I just repaired the script by Kubisz and ma.la.

Update - a new version of this script that plays nice with Google's new SearchWiki features, can be found here:

	Eh? You didn't like the indentation or something? I don't get it.

	[2008-11-21 00:43:49]Protector0ne says:
	Holy Balls. Google totally changed their result page. Naturally, the script is broken again. I will see if I can fix it soon(ish).

	[2008-11-21 02:29:05]Protector0ne says:
	Hold on. It still works when you're not logged in to Google. It's only borked in conjunction with Google's new wiki-search. Nevertheless, this script should still be fixed for said cases. I just fear it might be a little harder than expected. (With all those dynamically located search results and such.)
