Fix major security bugs (3 brushes + superpickaxe)! (#1213)
* Fix major security bugs (3 brushes + superpickaxe)! - Due to some recent changes, FAWE could edit everything in the world, no matter other plugin protections such as PS or WG. - Fix superpickaxe allow to bypass protections => Fix SurvivalModeExtent not taking into account protections plugins due to breaking blocks naturally to get drops. * Adress requests - Revert some unsuitabe changes - Add FAWE diff comments * Clean imports * Adress requests Co-authored-by: NotMyFault <mc.cache@web.de>
