Adds a check to see if JQuery mobile is supported, to the LightSwitch loading screen (default.html). This will catch most of the browsers that are unable to run LightSwich HTML apps (see note on http://janvanderhaegen.wordpress.com/2013/07/19/detect-if-the-browser-will-run-your-lightswitch-html-app/)

default.html extract

    <script type="text/javascript">
        $(document).ready(function () {
            var supported = $.mobile.gradeA();
            if (!supported) {
                $(".ui-icon-loading").hide();
                $(".ui-bottom-load").append('<div class="msls-header">This browser is not supported. Please upgrade to a more recent, <a href="http://jquerymobile.com/gbs/">supported</a> version.</div>');
            } else {
                msls._run()
               .then(null, function failure(error) {
                   alert(error);
               });
            }            
        });
    </script>
