Issue: Rewriting showwiki to itself

If the default settings are used, the Mod-Rewrite Generator tells you to add the following rule:
This seems kind of pointless when you think about it. When more than one .htaccess is needed, this appears in both .htaccess boxes. Neither issue seems to cause any problems, but it can be considered an inefficient use of server resources to process a meaningless line of code.

Fixed for the next build. This should only appear in the forum level .htaccess, and should only appear if the filename is NOT showwiki.
