This also moves the login pages to the login server, which makes the
code slightly a bit more contained. The account management page doesn't
allow you to do anything yet, but for future usage.
All accounts were sharing the same character list, but now they should
be properly separated. This also modifies the login database to prepare
for multiple service accounts, but there's no way to manage them in the
web interface yet still.
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.
This allows you to register in the web frontend now, and the login server now
checks this before giving a session ID. Note that this is wildly insecure (it
stores the passwords in plaintext!) and is duly noted in the USAGE.
