Handy for permission groups or separate config files per world.

extra option for included configs:

"default" - allows for setting up values that apply to all entries in that file (eg. default world, default groups, etc)

Code is mostly written. Option will be:

include-configs:
- fix_undroppables.yml
- leaf_drops.yml
- etc

Override setting will default to true (ie. any file loaded after another will override blocks for that type) - if set to false the file will add to the drops for that block type (possibly resulting in higher chance values than expected if both configs are dropping the same item - hence the default to override true).

Done in version 1.0 - default and only mode is no override (all included files have drops added to a global list).
