- matrix-receive node updated so that msg.sender is msg.userId instead (for better node chaining).

- change all references from msg.roomId to msg.topic to conform to Node-RED standards.
- Added node for listing Synapse users server-wide (as long as the caller is an admin)
- Events for Room.timeline are now handled by the server-config node and node's that listen for it bind a listener to that instead of the matrix client.
- Added kick and ban nodes for kicking/banning from a room
- Added node for fetching synapse user list using synapse admin API
- Added node for fetching whois data from a user using Matrix admin API
- Added node for deactivating users using the Synapse admin API
- Can register users using the Synapse admin endpoint v1 (yay legacy)
- Can add users using the Synapse admin endpoint v2
- Add more info to the readme.
