Improve handling of embedded YouTube.

We were scanning for »var swfArgs = {« but that seems to fail on quite a few pages I saw last week. (e.g.:

http://www.scienceblogs.de/mathlog/2009/10/mathematik-zum-anfassen-auf-youtube.php

It looks like the flashvars are stored after a »'SWF_ARGS': {« for those, so I'm scanning for that as well now.

A general YouTube change, perhaps? Does the old string still occur?
