Area deisgner: Add cooridante support

[icewolfz]

this requires a on/off field and an offset for x/y/z to allow you to determine how the area x/y/z is converted to "world" x/y/z

[icewolfz]

ShadowMUD supports coordinates on a per area base with linkage system, basic support is just enable i and add a x/y/z offset to know how to convert the logical coordinates to area coordinates

New Room properties

• coordinates: boolean = false; //default to off
• coordinateXOffset = 0; //the offset of the logical designer coordinate to convert to world coordinate eg designer x + offset == world offset
• coordinateYOffset = 0;
• coordinateZOffset = 0;

Another possible way is use an array of 3

• coordinateOffsets = [x, y, z]; in code and then convert to each in room editor to save space or keep them grouped

in visual editor have the 3 offsets editable and hide if coordinatesoff
display in read only mode the logical + offset under them as a preview
