* added optional password to the ContolSocket
* fixed possible exception/crash in the DefScript variable handler (occurred when typing "getvar" into the console or telnet). maybe a very slight code speedup, too.
* minor chat script updates (more telnet-friendly)
* note: if you use PHP or anything that is NOT telnet/netcat to send commands to the ControlSocket, you have to terminate each line with '\n' !
