Wesley Wolfe 7aabcb2ab3 Don't share WorldMapCollection. Fixes BUKKIT-4871
WorldMapCollection stores scoreboard, map (item), structure, and
village information. Scoreboards are explicitly handled globally,
while villages and structures are erroneously shared.

This commit separates the WorldMapCollections to not be shared among
custom worlds. Maps are special-cased to maintain the previous shared
behavior.
