interfacePrint is no longer directly called in non-interface contexts, but rather is handled by a messaging system. When one tile wishes to tell another tile a message, whether that be for descriptive purposes such as opening a door or otherwise, messageTile(Tile *sender, Tile *recipient, const char *message) is called. Within that, if the recipient->tid is PLAYER, then it calls interfacePrint. This will later be modified to check if the recipient->data->controller matches the actual user's controller (thus tying messages to particular users only). Also added was the basic struct for controller, but it is thus far unused in actual game code. The Controller will be used once a basic network/game structure is in order.
