Changes added to work on the Matrix public archive

See plan https://docs.google.com/document/d/1wP_TIqmBQjtt862vb2CWWmnmVxTyolcF3J1scuiYMdg/edit#

 1. Trying to make it faster/easier to build `hydrogen.es.js` for local linking and dev in `matrix-public-arhive` project
 1. Some random changes to accomodate using raw `EventEntry`'s
