* StandardCharacter now automatically invokes the Login command upon connection to the server. Login command not implemented completely yet.

* Telnet client header information is now successfully (finally) stripped out of the first stream received.
* Command System underwent some optimizations along with now always returning a Boolean value once execution of a command is completed.
* ICommand interface now forces all ICommand.Execute methods to return a Boolean value.
* DataPaths class re-wrote and is now simi in-use by StandardGame and the Login command
* Minor adjustments to how characters are initialized upon connection in various classes.
