Scope:

• Add group conversations accordion, which includes group-based conversations only (those conversations which were created based on a course group)
  • the data_for_messagearea_conversations web service (or relevant service) should be returning relevant metadata about the conversation's course/group, etc.
• Add group-based conversations support to search/results (again metadata from web service)
  • The web service should already provide you with relevant conversation metadata for each message returned (see MDL-63282 for details)
• Should be able to send/receive messages to/from the other group members within the conversation
  • Ideally, we'd (somehow) have a 'placeholder' representing a group-based-conversations in the UI, when no messages have yet been sent. This just means we won't have created the conversation until we actually use it. Still need to work out if/how - will mention this on MDL-63280 also - so check there too.
