logic: Group nodes in inheritance graph who have the same base and derived nodes (issue #459)

* added graph node for grouping nodes with separate sub-layout
* group nodes show name in top left corner
* clicking on single edge activates source locations of all edges
* removed separate setters for token components
* fixed text nodes missing or too many in list layout
* moved simple row and column layouts to ListLayouter
* added skewed layout type to ListLayouter
