Chat System Code

Not sure what I did.

Changed port that it runs over to 4444, and changed the way it procures a socket so that it can handle IP addresses and FQDN

Almost finalized the final pieces for the checking of the user name. NEEDS TESTING!

More stuff

Added some more functions to check if the user exists.

Added server support for checking for usernames that might already exist.
NOTE: The usernames are case sensitive.

Added the function userExists() for testing if the username has already been taken.

Initial import.
