MudEngine:

- Added BaseCharacter.FlushConsole() method. Sends a hex sequence to the clients telnet terminal that clears the screen. If IsMultiplayer=false then it just clears the C# Console.
 - Added a 'Clear' command for users to use. It invokes the new FlushConsole command.
 - Removed the need for a full file path and filename when calling an objects save method. Now it just needs the path.
 - Adjusted the Exit command, Login command and Save command to reflect the objects save parameter changes.
 - Removed the Unique ID from objects. 
 - All objects now reference each other via their filenames rather than their object names. Allows for 3 objects with the name Bedroom to exist, but with different filenames such as Bedroom1, Bedroom2 etc.
 - Zone now has a GetRoomByName method that replace the removed GetRoomByID method. Returns a List<> collection of Rooms found with a matching filename.
 - BaseCharacter updated to work with the new Zone.GetRoomByName method.
 - Realm.GetZoneByID renamed to GetZoneByName()
