Title: Serialization of multiple data attributes

By changing:

item = { id: li.attr(list.options.itemIdAttribute) },

To:

item = li.data(),

All data attributes will be serialized, i think this is useful, as it allows the user to specify extra attribues and pass custom data to the serialized string
