Prefix for item is forced since 2.0

Line 775 - 797

`
id = ($(item).attr(o.attribute || "id") || "").match(o.expression || (/(.+)-=_/));

if (depth === sDepth) {
pid = o.rootID;
} else {
parentItem = ($(item).parent(o.listType)
.parent(o.items)
.attr(o.attribute || "id"))
.match(o.expression || (/(.+)-=_/));
pid = parentItem[2];
}

if (id) {
var data = $(item).children('div').data();
var itemObj = $.extend( data, {
"id":id[2],
"parent_id":pid,
"depth":depth,
"left":_left,
"right":right
} );
ret.push( itemObj );
}
`

The problem here is the expression and the usage of id[2]. Because of id[2], you always have to define a prefix, because if you don't, you can only access id[1] and not id[2], which is not existing. The expression "(/(.+)-=_/)" should be "(/.+-=_/)". And instead of using id[2], you should use id[1]. This would allow me to use another attribute like "data-id" with the id as a value, without an "item-" prefix.

Sorry fot not pulling a request, but at the moment I not not have capacity for this.
