show d3-logicnames only up to the first dot-char

- Since the names of Logics can be rather long,
  because they can display the path of a Sublogic,
  we only display the name up to (and including)
  the first dot-character (which is the Sublogic-
  Separator)
- We will still show the full name in the
  detailed view to the right of the graph.
add ability to include more logic-mapping info.
