Build in imageLoaded.js

[liammday]

I've found it useful to incorporate imageLoaded.js to the NProgress.done(); function. Could this be built in to the core script rather than the end user having to combine the 2 scripts?

@liammday try this

`` NProgress.start(); $(document).ready(function() {

$('body')
    .imagesLoaded({ background: true })
    .always(function() { NProgress.done(); })
    .progress(function() { NProgress.inc(); });

    $('#container')
        .imagesLoaded({ background: true })
        .progress(function() { NProgress.inc(); })
        .always(function() {
            NProgress.done();
        });

});
