Tidy was only being used by a couple of non-default URL shortener plugins, PtitUrl and TightUrl. Both were easily changed to load the tag-soup HTML via DOMDocument (using the default DOM module which is already used by other dependencies). Added xml, dom, and simplexml modules to the requirements check in install.php, as they were being used but not checked for. Also cleaned up LilUrl, PtitUrl, and TightUrl to return URL as a string instead of as a SimpleXML node object.
