Using Promise-compatible instead of Deferred-compatible

[AurelioDeRosa]

In the page about $.Deferred the text asserts:

In most cases where a jQuery API call returns a Deferred or Deferred-compatible object, such as jQuery.ajax() or jQuery.when()

I think it'd be better to call these objects Promise-compatible because objects like jqXHR implement the Promise interface (source), so they can't call methods like resolve() or reject(). I know this is a very minor change but it seems reasonable to me.

Makes sense to me, too.
