If true, this option will cause wave numbers to be displayed as the
players' level to aid in wave tracking. It does NOT replace the
announcements, which can still be disabled by putting blank values
in the announcements-file.
This is an extremely ugly, hacky way to do it, but the feature
should definitely make it into 1.0 - it requires no commands or
any other complex setting up besides flipping one option in the
config-file.
Upon clicking a class sign in the lobby, MobArena will (if the
config-setting is true) search for chests below the sign, and
below (and including) the block behind the sign, i.e. the block
that a wall sign would be attached to. If a chest is found, the
contents will become the class inventory.
The search can be optimized to be a one-off thing unless the
block changes from being a chest. A todo for 1.0, perhaps.
