Room management logic

The chat service fundamentally sends and receives messages via irdest-core, processes them in some form, and generates new events available via its API.

The basic room logic needs to be able to handle the following events:

• Manage room state
  • Create a room
  • Invite a new user
  • Kick a user
  • Set a room name
  • Set a room avatar
• Send a text message into a room
