Restructured the project save data folder layout when the engine starts.
The XMLData class now creates directories if they are missing. Individual classes no longer need to check if a path is valid before saving.
Filenames are now automatically generated and no longer assigned by developers. This change has been made across all classes that are savable which required some changing of the Save() method arguments.
CharacterRole class created with helper static methods for converting strings to their correct CharacterRoles enum value.
Environment class has save/load support however Realms/Zones/Rooms do not yet.
Newly created characters are assigned to the new World.StartLocation.
Rooms can now be connected.
Realms and Zones can create Zones and Rooms accordingly
Force moving of a character is now supported. Walking has yet to be implemented.
