Artifact simplification (#2781)

* #include an absolute path didn't work - because paths were taken to always be relative.

* WIP simplifying artifact interface.

* Use ContainedKind.

* Remove LazyCastableList.
Use ContainedKind for find.

* Remove ICastableList.

* Remove need for ICastableList.

* Remove IArtifactContainer.

* Small fixes.

* Small improvements around Artifact.

* Make explicit find is for *representations* that can cast.
Fix bug in handling casting in lookup.

* Made associated items artifacts too.

* Small fixes.

* Small improvements around writing a container.
