Implement #17.
Flattens all tiles in the floor plan upon entering a room while enabled.
Allows the user to toggle height translation on/off.
When height translation is on, locations are negatively offset to the flattened floor tile.
Otherwise floor items/entities appear at their usual, unflattened locations (some wall items may still appear in the wrong locations due to the flattened floorplan changing the base wall height offset).
