Clean up Async Code to define clear stages based on state

[bushidocodes]

@Jmikeydarby spitballed a pretty good sequence of atomic stages that we can use to bring some sanity to how we handle the lifecycle of a client joining our server. Awesome idea, not enough time. This is filed away for use later when we want to keep this project improving.

Stage One: Login
Stage Two: socket connection
Stage Three: get all data
Stage Four: Render
Stage Five: Initiate WebRTC Handshaking and Peering

This approach should be extended to include transportation between scenes, planned logout, and unplanned disconnects.
