This would basically mean instead of having IDs looking like $ they'd be something like: 7EQORdPaApfus7VgUPyupQ9d7P574HbgqqNKzgY7RoE.

This would then mean that hashes wouldn't need to be included when referencing events in e.g. prev_events.

Open questions include: how do we specify the type of hash? Or do we mandate e.g. sha256 and if we want to change we create a new room version?

A fuller writeup will be along shortly. see PR #1659
