Updated TNT explosion protection to cover TNT minecarts

Added trapped chest, hopper, and dropper to default territoryProtectedMaterials and territoryProtectedMaterialsWhenOffline lists

Existing users will need to update their config to add these, like so:
/f config territoryProtectedMaterials TRAPPED_CHEST
/f config territoryProtectedMaterials DROPPER
/f config territoryProtectedMaterials HOPPER
/f config territoryProtectedMaterialsWhenOffline TRAPPED_CHEST
/f config territoryProtectedMaterialsWhenOffline DROPPER
/f config territoryProtectedMaterialsWhenOffline HOPPER

Also cleaned up some leftover code
