RedFreez

New features:

• Complete freeze — pistons and hoppers/droppers are now also blocked in frozen chunks (previously only redstone was blocked)
• Frozen chunk entry notification — action bar warning when you walk into a frozen chunk
• Async chunk scanning — /rf scan no longer blocks the main thread
• /redfreez reload command — reload config without restarting the server

Config additions:

• freeze.block-piston-event
• freeze.block-hopper-transfer
• freeze.notify-on-enter
• bridge.max-copy-amount
