OtherSVNBackedWikis - from r1043 to r1044

There are a few other SVN backed wikis.

* svnwiki (active, scheme, http://wiki.freaks-unidos.net/svnwiki/)
* subwiki (defunct?, python, http://subwiki.tigris.org/)
* ikiwiki ('wiki compiler', svn or git, http://ikiwiki.info/)

* JSPWiki (active, creole mark-up, Java, http://www.jspwiki.org/ with http://www.jspwiki.org/wiki/WikiCreole and http://www.jspwiki.org/wiki/SubversionProvider)

The first two got the good names. In fact, reviki was called svnwiki for a while as I failed to find svnwiki until I was a good way into reviki.
