===========================
- Added support for displaying lines in a tree (Stephan Richter)
- Changes in `Node.getFlatDict()` to provide more data. Removed
'depth' from node info, but added 'row-state' and
'last-level-node'. Changed interface and test accordingly.
- Updated templates for `StaticTree` skin and example. Note that
third party templates from 1.0.x will not work anymore and must be
updated as well!
