-- ObjectRef is basically ServerActiveObject.
-- ObjectRef methods:
-- - remove(): remove object (after returning from Lua)
-- - getpos(): returns {x=num, y=num, z=num}
-- - setpos(pos); pos={x=num, y=num, z=num}

-- - add_to_inventory(itemstring): add an item to object inventory
--
-- Registered entities:
-- - Functions receive a "luaentity" as self:
-- - It has the member .object, which is an ObjectRef pointing to the object
-- - The original prototype stuff is visible directly via a metatable
