Removed includes/phpsvnclient.php
phpsvnclient.php was previously used to interface the Four Island Subversion Repositories so changesets could be seen via the RSS feed, but not only
not many people want this in their RSS feed, and the people that did could get a seperate feed, but Four Island no longer uses Subversion, instead it
uses the better, distributive Mercurial.
