trigger event after setCurrentLayout is done in omega-mediaqueries.js

This is needed to calculate the page sizes correct by javascript and apply scroll events or somthing like this.

I tested it to replace the folowing:

        $(window).bind('resize.omegamediaqueries', function () {
          setCurrentLayout(dummy.css('z-index'));
        }).load(function () {
          $(this).trigger('resize.omegamediaqueries');
        });

by

        $(window).bind('resize.omegamediaqueries', function () {
          setCurrentLayout(dummy.css('z-index'));
          $(this).trigger('resize.omegamediaqueries.done');
        }).load(function () {
          $(this).trigger('resize.omegamediaqueries');
        });

For me this works fine and I got no longer race conditions between load event and the manipulation of the media query classes.

Thank you.
