Prevent flickering / going back and forth #273

First of all, thanks a lot for this module, it is awesome! I just had the problem that sometimes different requests weren't really combined to one loading bar but instead it was going back and forth multiple times. What fixed it for me was simply preventing to set the status to a lower value:

       var oldSet = cfpLoadingBar.set;
        cfpLoadingBar.set = function (n) {
            if (n > cfpLoadingBar.status()) {
                oldSet.apply(cfpLoadingBar, arguments);
            } 
        };

Is there any reason not to use this condition?
Cheers,
Jesse
