		NOTE:
			the nickname is required by the server, if not specified
			the message may not be sent unless a command was intended
			which requires another packet to be constructed! you can
			achieve this by putting a slash ("/") infront of the
			message followed by the command name and the message.
			of course all slash-commands need implemented handler-
			routines. ;-)
			remember, a line starting w/ "@" is not a command that needs
			to be parsed rather is sent using the normal chat-packet.

		EXAMPLE:
			// for an global announcement   /- command
			chatlog.chat_send("", "/announce Hello to all logged in users!");
			// for simple message by a user /- message
			chatlog.chat_send("Zaeiru", "Hello to all users on the screen!");
