title: modernizr duplicates scripts when resizing screen
body: <p>i'm placing scripts with modernizr for specyfic screen widths. Everything works fine for initial load but when I change tablet orientation from portrait to landscape there are two problems: scritps wpn't be loaded at all or modernizr will duplicate them every time i will switch to given orientation. See the code I'm using:</p>
  
  <pre><code>        Modernizr.load([
              {
                  test : Modernizr.mq('screen and (min-width: 600px)'),
                  yep : ['/js/supersized/js/supersized.core.3.2.1.min.js','/js/supersized/css/supersized.core.css'],
                  complete : function() {
                      if(Modernizr.mq('screen and (min-width:600px)')) {
                          jQuery(function($){
                              $.supersized({
                                  fit_portrait: true,
                                  slides  : [
                                      {image : img/sample.jpg', title : 'sample'}
                                  ]
                              });
                          }); 
                      };
                  }
              }
          ]);
  </code></pre>
  
  <p>so when changing orientation from below 600px to bigger one (after loading in narrower version) it doesn't load the script.
  But when I add $(window).bind('resize', function(){   it keeps adding scripts and css to head ( so i got like a lot of scripts of supersized attached to head).</p>
  
  <p>So basically the question is: is there any chance for modernizr to check on window resize if the script has ben alerady once included or is there a posibility to remove script from head when resizing below specified breakpoint (in my case 600px).</p>
