animate() with empty params object == nothing

[strager]

Calling animate as such:

myJQueryObject.animate({}, 2000);

Freezes the animation queue. Next animation doesn't start after 2s; everything just seems to stop.

(I was doing this to have a pause in between animations. Maybe there's a better way to do this?)

You could use a fake attribute, or an irrelevant one. I'll check this out asap.

Yeah, I used {opacity: '+=0'} as a temporary fix and it worked fine (didn't change opacity).

I think we just need to move the test for an empty object inside the each/queue and call the completion function.
