[Seaside] JQDroppable convience method

I've quickly added some convenience methods to JQAjax that serialize
the information of the jQueryUI events:


All these callbacks expect a block with one argument that gets
evaluated with a dictionary of the event elements as documented in the
jQueryUI documentation.

Johan, your code would now look like this:

    ... onDrop: (html ajax
        callbackDroppable: [ :event |
            (event at: #draggable) doSomething ])

Note that I also renamed #trigger:passengers: to
#callback:passengers:, that fits better the jQuery protocol.

Let me know if this is useful or if there is something else missing.
This is mostly untested functionality so expect to encounter bugs.
