Share very short codes to join other documents

[adzialocha]

We want users to be able to use very short "invite request codes" which resolve to full document hashes, for example 4686 could resolve to 4686debd13ab5276665c6a163860ee70135d61123d3aba016f4825824f5b5cd7 through a flow in the backend where other peers get asked to resolve it for you (and returning multiple options if collisions occurred).

This would not allow the user access to the document yet but they have an identifier now and can request access.
