Add commands to handle referenced by relation and references relation

Analogous to call graph and caller graph this patch provides an implementation for the referenced by relation and references relation.
Providing the commands:
- referencedbyrelation
- hidereferencedbyrelation
- referencesrelation
- hidereferencesrelation

Motivation is that some lists can get extremely large and also there is now more symmetry between the textual and graphical out.
