create archive package, archive-entry model and add to .asd file.

This is a rough sketching out of what the model/data needs to look
like. This model is what will be connecting the site's archive (Nic's
artwork entries) with the Meilisearch service -- running alongside
each other. I don't know how much this model is going to change but
expect it to in future commits.
