When sqlickrypt is run with the option "register", it expects a
username, password, and email, and adds them to the database if the
username is not already in use.
The quickrypt utility is replaced with sqlickrypt, which takes a username
and password pair and checks them against the SQLite password database
used by dgamelaunch. This will be more extensible to using rlgwebd to
register, change passwords, etc.
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.
Implement checking the numbers of the client's messages on the server.
Fixing out-of-ordering isn't implemented because the problem hasn't
been observed yet, though it likely will once actual network transit
is involved.
Make sure data from the server is written to the terminal emulator in
the correct order. Out-of-order messages are stored in a queue until
their turn comes.
