* Remove documentation links to board.s9y.org
The 'website' property of plugins is used to
link to external documentation. board.s9y.org
does not contain such documentation, at least
not on its frontpage.

* Remove dead documentation link.
c.seo-mobile.de does not exist any more.
According to
http://www.mobile-seo.de/archiv/21-serendipity-mobile-output-plugin.html
all documentation has been posted (only) there,
so is gone now.
