Thanks to everyone for reporting, here is a list of fixed issues:
- alternative JSON format works with types
- most functions did not work correctly when arrays of nodes were passed in
- multitree drag n drop now works as expected
- renaming a node did not allow mouse interaction (could not click on input field)
- there was a huge bug with node li_attr being shifted to the next node
- html is now handled properly (in titles)
- added set_id function
