Distance option default

The default value for the distance option should be changed to 1 (currently 0) for plugins that use the mouse plugin. Otherwise in order for clicks go through you have to explicitly set the distance to 1 (or higher). This is the more common case (click without moving=click; move 1px=drag), and should thus be the default. See

Those are all sortables examples, but the same is true for selectables, draggables, resizables (slider already has 1 as default).
