SpawnerAdjuster

Changes from 1.6.0 to 1.7.0:
-Added advanced setting to make spawners non-interactable if you lack the permission to change them
-We now track Entities rather then LivingEntities. Perhaps we could extend this one day to allow spawners to spawn things like minecarts/snowballs/items, but for now its mostly a bug fix.
-Blockplace events are no longer prevented when interacting with a spawner.

Known Issues:
-Radius check sometimes wonkey. Just disable if you have issues.
-included config file is slightly out of date. Run SpawnerAdjuster once and it will update the config file.
