Engine:

- Changed the IGameCommand Interface constructor for the Execute method.
 - Updated all of the game commands to make use of the new Execute Method Constructor requirements set by the updated interface.
 - Look command now returns a description of the players current Room.
 - Walk command now supports moving players from one Room to another. Use 'Walk Direction' where Direction equals the direction you want to travel (Example: 'Walk North")
 - TravelDirections.GetTravelDirectionValue now checks the supplied direction value in a case-insensitive manor.
 - Add a new CommandEngine that handles the commands inputed from the user.
 - Modified CommandResult to return an array of objects rather than a single object.

Runtime:
 - Now scans the supplied collection of objects returned to the runtime after executing a game command, and adjusts the runtime components as needed, including printing information to the console.
 - Now displays various warnings during startup to let the user know if certain content hasn't been set within the ProjectInformation yet.
 - Now executes the 'Look' command on startup to display the users current location.
 - Fully supports the 'Look' and 'Walk' commands.
