Subject: [PATCH] Entity load/save limit per chunk
Adds a config option to limit the number of entities saved and loaded
to a chunk. The default values of -1 disable the limit. Although
defaults are only included for certain entites, this allows setting
limits for any entity type.
1.17: looks like tracking the count on loading should work fine just putting it in the EntityType#loadEntitiesRecursive, but
the tracking count on save needs some more work to implement.
