Adding ephemeral detail string to Room GMCP, focing mapper to use low…

[Volte6]

Description

This forces the mapper to use the lowest RoomId in the set as the 0,0,0 origin. This solves the issue of drifting coordinates depending on what gets mapped first.

Changes

• Added x, y, z offsets based on lowest room in mapper.
• Added ephemeral to Room GMCP payload (Details) when a room is ephemeral.

Examples

without changes (Force to generate dark forest first):

Room.Info {
        "num": 1,
        "name": "Town Square",
        "area": "Frostfang",
        "environment": "City",
        "coords": "Frostfang, -18, 1, 0",
        "exits": {
                "east": 54,
                "north": 2,
                "south": 12,
                "west": 7
        },

With changes (Still forced to generate dark forest first):

Room.Info {
        "num": 1,
        "name": "Town Square",
        "area": "Frostfang",
        "environment": "City",
        "coords": "Frostfang, 0, 0, 0",
        "exits": {
                "east": 54,
                "north": 2,
                "south": 12,
                "west": 7
        },

Looks good to me. Tested it locally and it mapped like a champ.
