Removed require of Loofah in testing.rb. It's required in the assertions.rb file.
Renamed html-selector to html_selector. Moved NO_STRIP to html_selector. Required the correct path in selector_assertions.
Required loofah in test file. Got the tests to run. Setting the @response to nil in setup. Fixed reponse | response spelling error in render_html.
reset @html_document to nil whenever render_html or render_xml is called. Fixes remaining test failures.
