Version 0.2.4

- Can now configure a room on the invite-room node (instead of having to pass it in on the msg)
- Changed how the connection event was handled by nodes
- matrix-synapse-join-room node was broken (was trying to access a variable that was never defined).
- olm library updated to 3.2.1 to hopefully fix "account.generate_fallback_key is not a function" Fixes #26
- Added description to the server configuration node that describes how to create a user for use with this module
- Update link to create room api for matrix-create-room.html
