Feature request: dependencies --no-owns

[wduminy]

Thank for for creating this great utility.

A new option --no-owns on the dependencies command would help me to create a cleaner usage graph.

Looking at the graph below, applying the --no-owns option could create a view that shows only the uses links.
Perhaps also removing those nodes that do not participate in such a relation.

This seems related to #265.
