Fix jQuery adapter to work with newer versions of jQuery, specifically:
newer jQuery returns true when asking if a text node matches the selector *, where previous ones did not.  Internal tinyMCE DOMUtils returns false, as did prior versions of jQuery

Add a test case that tries to match * against a DOM node and a text node
Add a test suite that runs the tinyMCE DOMUtil jquery adapter tests against jQuery 1.8, which shows this bug
