Add the Ability to Use QUnit.config Options

[lenzi-erickson]

I would like the ability to use the options located here: http://api.qunitjs.com/QUnit.config/. Something along the lines of this:

gulp.task('test:qunit', function() {
                return gulp.src(config.jsPath + '/tests/index.html')
                                .pipe(qunit({hidepassed:true}));
});
