minetest.place_schematic(pos, schematic, rotation, replacements, force_placement)
^ Place the schematic specified by schematic (see: Schematic specifier) at pos.
^ Rotation can be "0", "90", "180", "270", or "random".
^ If the rotation parameter is omitted, the schematic is not rotated.
^ replacements = {{"oldname", "convert_to"}, ...}
^ force_placement is a boolean indicating whether nodes other than air and
