Diagram tweaks #1

- relaxed the restrictions on nodes - nodes can be classes, traits and
objects, both stand-alone and companion objects -- all are added to the
diagram, but usually companion objects are filtered out as they don't
have any superclasses
- changed the rules for default diagram creation:
  - classes and traits (and AnyRef) get inheritance diagrams
  - packages and objects get content diagrams
(can be overridden by @contentDiagram [hideDiagram] and
@inheritanceDiagram [hideDiagram])
- tweaked the model to register subclasses of Any
- hardcoded the scala package diagram to show all relations
- enabled @contentDiagram showInheritedNodes by default and changed
the setting to hideInheritedNodes (and added a test for this)
- better node selection (can select nodes that don't have a
corresponding trait)
- fixed the docsite link in member selection, which was broken since
the first commit :))
