New regression tests; fixed existing tests; bumped version

- Added a regression test for the previous media rule fix
- Discovered all existing test cases failed because jsdom.html() -- called by /lib/utils/jsdom() -- wrapped all those /test/cases/*.out files with \<html\>\<body\> and \</body\>\</html\> tags which wasn't expected
- Fixed (?) those test cases by adding missing html & body tags
- Added a regression test for this case as well (/test/cases/jsdom.*)
- Bumped the version to 0.0.7 so a new npm can be published and used by projects like mine that depend on it :)

FYI here's the code in **jsdom** that appears to add the html & body tags:

    exports.html = function(html, level, options) {
      html += '';

      // TODO: cache a regex and use it here instead
      //       or make the parser handle it
      var htmlLowered = html.toLowerCase();

      // body
      if (!~htmlLowered.indexOf('<body')) {
        html = '<body>' + html + '</body>';
      }

      // html
      if (!~htmlLowered.indexOf('<html')) {
        html = '<html>' + html + '</html>';
      }
      return exports.jsdom(html, level, options);
    };
