BGCOLOR now follows the same default as IupText and IupList, and can be changed. New TITLEFONT, FGCOLOR, USERDATA, FINDUSERID, COUNT, CHILDCOUNT, EXPANDALL, INDENTATION, HIDEBUTTONS, HIDELINES, COPYNODE, MOVENODE, SPACING, TOPITEM, INSERTLEAF and INSERTBRANCH attributes.

ATTENTION - DEPTH is now a read-only attribute, use the INSERT* attributes to properly add nodes. NAMEid attribute renamed to TITLE, old attribute still works but will be removed in future versions since it conflicts with the common NAME attribute. The SELECTION_CB and MULTISELECTION_CB callbacks now ignore their return value. The rename action is now activated by two clicks instead of a double click.
