Support easing callbacks, instead of only strings

Currently easings args accept only strings (

for instance). The idea is to support callbacks. So you not need set your easing to public.

  var my_easing = function(a, b, c, d, e) { ... }
  el.animate(..., my_easing);

I guess that the problem can be the conflict between the complete callback and the easing callback. Javascript can check the callback args length.

Easings have 5 args, and complete callback no one.

So maybe it can be done:

Function.prototype.length is meaningless in a language that allows variable arity calls to functions with defined formal parameters.

jQuery provides jQuery.easing as a place to hang your custom easing functions.
