Inception

#2644 R3 -> #2644 R4

• Fixed typo in 'config.yml'
• Seperated SafeGlass from Safe option, to prevent abuse with glass.
• Seperated Lower.Safe from Lower.PreventFalldamage.
• Fixed bug in Handler and HandlerTickTask which would prevent it from working with certain configurations.
• Optimized EnumSet away, now using Arrays. Might use up to 100 bytes more per world, depending on your filter.
• Optimized Handler to skip a few calls to methods not really needed. Should make servers with many users faster.
