This change moves nested layouting of the Graph to GraphController. The DummyNodes get the correct size assigned, as
well as a visible flag. Mouse interaction with the Graph is now handled via the GraphController, which makes it
easier to undo them or reuse the changed state after graph updates.
This change styles the nodes in the QtGraphView. Since Stylesheets can't be applied to QGraphicsItems, the style
implementation was done in the source files. The containers for public/protected/private nodes are now subclassed from
QtGraphNode as QtGraphNodeAccess, including a helper class QtAccessArrow for indicating the opened/colapsed state.
* fitting boxes to name length
* highlighting active edges and nodes
* hover for edges and nodes
* single click selection for edges and nodes
* edges have transparent second line for easier clicking
* sub structure class members by public/protected/private
By now the graph displays the active node, without neighbours or anything, and clicking a node sets the active token id to the clicked nodes id.
