[slrn-doc] 0.9.9 release

[Peter J R. <pea...@gm...>]

I've released the current html and txt documentation here:
<https://sourceforge.net/project/showfiles.php?group_id=4526>. I've updated 
<http://slrn-doc.sourceforge.net/> accordingly, and posted a link in NSR.

I've also added branches/0.9.9/ to the svn repository. Bugfixes to the 0.9.9 
documentation should be made in this branch. trunk is now available for 
experimentation.

Thanks, everyone!
