[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
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.
