Updated to QUnit 1.14.0
Changed .show and .hide to .css("visibility") calls to fix odd layout issue of the #button-row.  Changed <a> to <button> tags and updated popup.css with % widths.
Use FileReader() and Blob() API to directly import and export .rdf files to & from the Firefox version. This solves issue #41.
