LOC-9: Release Notes

This issue will, for now, serve as the release notes for this project until I have more time to write them up properly.

v0.0.1a is a Proof of Concept release intended only to contain the most basic functionality required to start working towards the design.

It implements both the client and the server software, with the following features:

- Client can create rooms
- Users can be "invited" to an existing room (basically authorising them to join, no invite is sent)
- Messages in the room flow back and forth
- Users can leave the room

Version 0.0.1a is not considered suitable for production use in any way, and should not be deployed as it lacks numerous protections - ranging from exception handling to E2E encryption.

It exists purely as a starting point for this project.
