+Concept of stuff to do:
+
+1)	Implement a flag for invisibility in IPlayer (interface) and make sure that
+	any and all things that use IPlayer update this flag.
+
+2)	Implement a check box in the connection GUI.
+
+3)	Use the check box from 2) as a flag in the connection.
+
+4)	Add a key for invisibility whilst spectating/invisible during a game
+	This will serve as a toggle.
+
+5)	Reuse code as needed.
+
+6)	Suppress connection messages when joining as invisible; show disconnection
+	messages and connection messages if applicable when joining as non-invisible.
