sortable: should reset elements when return value is false

[phpmyforum]

I think it would be great if we could "return false" inside these callbacks to tell jQuery that it should reset/cancel the sort action:

• stop
• update
• sort
• change
• maybe "start" too?

This can be useful if you do a Ajax call to save the sorted elements which fails or the backend prevents the action for a different reason. In this case the element should revert to it's previous position.

This is unfortunately not possible from a user perspective - since the user is still holding down the mouse, and therefore dragging.

Anyway, if the ajax call was not successful, nothing prevents you to sort the elements again in the stop callback.
