Did some refactoring concerning handling of unrecognized commands, but these are still not printing correctly.
Responses for when the user specified unclear commands now prints _more_ correctly than before. However, there are still erronous responses for when the player attempts to travel to locations to which he/she cannot.
Now printing better responses when the user types inconsistent input, or the game does not interpret commands correctly. Executioner may now recieve Result-type objects for parsing messages when the interpreted action cannot be performed correctly.7
