The user now logs in with a username and password, receiving a token
which is then used for any actions requiring authentication. Starting
a game is one such action. Games use a different set of id keys.
This allows users to supply their passwords once and then play any
number of successive games. Also, newly registered users do not need
to supply their passwords again.
For roguelike games, most output will directly result from and follow
immediately after input from the user. In other situations, data
should not be expected.
The RLG-Web server can now be controlled with commands sent to stdin.
Currently, the only one implemented is "quit". Some improvements to
the shutdown process were also made.
Port the JSON communication from WebTTY to RLGWeb. Fixing out-of-order
messages is still not implemented on the server side. Terminal size is
still hard-coded. Unused code is still lying around.
