--  scm="bla"		Name of the file that holds the buildings' schematic. Supported types: .we and .mts (omit the extension!)
--  sizex, sizez, ysize: obsolete
--  yoff=0		how deep is the building burried?
--  pervillage=1	Never generate more than this amount of this building and this type (if set) of building per village.
--  axis=1		Building needs to be mirrored along the x-axis instead of the z-axis because it is initially rotated
--  inh=2  		maximum amount of inhabitants the building may hold (usually amount of beds present)
--			if set to i.e. -1, this indicates that a mob is WORKING, but not LIVING here 
--   we_origin		Only needed for very old .we files (savefile format version 3) which do not start at 0,0,0 but have an offset.
--  price               Stack that has to be paid in order to become owner of the plot the building stands on and the building;
--                      overrides mg_villages.prices[ building_typ ].
--  guests		Negative value, i.e. -2: 2 of the beds will belong to the family working here; the rest will be guests.
--                      For building type "chateau", guest names the number of servants/housemaids instead of guests.
