Custom Matrix types

eu.steffo.meta.twom.party: room type used to distinguish TwoM parties from regular rooms, which are hidden.
eu.steffo.meta.twom.rsvp: state event type used for the user's response to a party invitation; uses the replying user's mxid as state key, and has an object with the following keys as payload:
- eu.steffo.meta.twom.answer: a string containing one of these values, indicating the user's presence at the party:
  - "SURE"
  - "LATER"
  - "MAYBE"
  - "NOWAY"
  - ""
- eu.steffo.meta.twom.comment: a string containing an user's freeform comment provided in addition to the answer.

Avatar URLs are sometimes fetched before they're available on the homeserver, causing them not to be loaded correctly on party creation.
Due to API limitations, the app does not check if the user has permissions to perform certain actions, such as changing the name of a party, and instead returns a MatrixError when the action is attempted.
Due to Matrix protocol limitations, any user can change other users' party replies by sending custom state events, even though this app itself does not allow it.
