Disallow placing entities outside safe boundaries
Entity positions are serialized as F1000. Disallow placing
entities outside safe borders with the minetest.add_entity
call.
Note that this patch only enforces those boundaries for
placing entities, moving entities that move outside boundaries
aren't affected.
Thanks to @nanepiwo for pointing this out.
