MOTD contents are now read from a file that can be easily updated
Moved the sending of MOTD and other registration messages from PONG to the authentication helper
Delayed the sending of registration messages when PASS authenticating
Added support for MOTD command
Additional changes/comments:
Send the common "We are processing your connection" message once connected, so it doesn't feel as it got somehow stuck if the PASS authentication takes a little while.
Understand commands sent in lowercase
PONG now just stores the current timestamp that can be used when we implement a periodic timer to do pinging. It could just be removed for now, though.
