different values for snapTolerance by direction

[detlevv]

The snapTolerance could be different by x- or y-direction. This is useful, if the user wants to snap only in one direction oder with different tolerance values.

This could by done by accepting an optional array like this:

drag: function(event, ui) {

var inst = $(this).data("draggable"), o = inst.options; var dx = (typeof o.snapTolerance !== "number" ? o.snapTolerance[0] : o.snapTolerance),

dy = (typeof o.snapTolerance !== "number" ? o.snapTolerance[1] : o.snapTolerance);

After that the code should use dx or dy as appropriate.

We'll be removing snapping from the core of draggable during the rewrite, so we won't be modifying the API at this time.
