Now the world isn't hardcoded to Gilgamesh, and is configurable. It's also now
the "Dev" server listed in the excel sheet which makes a more sensible default.
This is unfortunately lumped into one big commit, and is very hacky and WIP but
does indeed work! Since the Lobby and World server are two separate servers, it
uses it's own custom IPC packets (reusing the same packet structures as regular
game ones.)
The characters you create in the Lobby server are now saved in the World server,
but this is not yet reflected in the Lobby screen.
