Title:  Update select2.sortable.js

Added support for group of elements in select2SortableOrder function.
Check if the select is already select2-ed in select2Sortable to prevent previous select2 configuration loss.
Modified select2SortableDestroy to destroy only jQuery UI sortable and non not select2 entirely.

Let me know what do you think, I'm here to discuss every detail.
