xshxdex98 9d309f8d75 Refuse a Custom Edition map of another version than the host's ...

A client joining a game on a Custom Edition map checked only that it had a
file of that name. With another version of the map (an older release, a
re-edit), its tags are not the host's: the objects, weapons and vehicles the
host sends are other things there, and the game desyncs or crashes.

The host now sends its map file's header checksum as the game record's map
version, which the Xbox game always left 0, and a client whose copy has
another checksum leaves with an error saying so and where to copy the
host's. The record's layout is unchanged: a host that sends 0 (an older
one, or the game's own maps, whose builds of other regions play together)
is not checked, and older clients ignore the field.
