Do not use Object as descriptor key, use dedicated type. And intern the List<Dependency> on artifact descriptors. Also introduce "intern"-ing of ArtifactDescriptor dependencies and managedDependencies that is configurable (speed vs memory).

Do not use Artifact instance as keys, and intern the
List<Dependency> on artifact descriptors as well.

(default: false to both, as before)

Adds two new config properties that controls interning of
ArtifactDescriptor dependencies and managedDependencies.

Interning both radically lower memory consumption but at
same time increases runtime.
Intern only managed deps.

Also simplify a bit.
