Artifact assets can now be copied server-side between artifacts without downloading them.

The artifact tool's asset store now supports a copy_from action that copies assets from one artifact into another entirely server-side, with no download or re-upload. It takes a destination url, a source from_url, and up to ten asset_ids, and requires the requesting session's approvals to cover the copied files ("files: copying another artifact's file needs the user's approval"). Reading an artifact's assets now also covers server-side copies of them into other artifacts.
