3.0.0-beta3

Thanks to everyone for reporting, here is a list of fixed issues and changes:

• component.io support
• fixed bug where selecting a node would not open to the node (even if the supress_open param is false)
• added a param to get_selected which if set to true makes the function return an array of objects with full node details, and not just IDs
• now get_json returns node type too
• fixed state not restoring opened nodes properly
• added option to search plugin which closes all nodes opened to reveal search results once the search is cleared
• create_node respects node.id
• fixed set_id and set_icon bugs
• fixed rendering in IE8
