TekkitRestrict 2.1

What does this fix/add?

• Chunk Unloader now works. After the specified MaxChunks, it will go into a Turbo mode that can unload chunks on all worlds at once.
• Environment-specific MaxChunks on the ChunkUnloader did not work, along with load order so they have been disabled.
• Fixed several grammatical errors for dupes/hacks.
