Textile Backup

What's Changed:

• Fixed #123 - Improper call to MinecraftServer::saveAll leading to various exception during backup creation
• Fixed #130 - Missing CRC checksum on single-threaded ZIP
• Fixed #122 - BZIP2 producing empty files due to missing call to the actual compressor

• Implemented #125 - TxB no longer enables world auto-saving for dimensions that didn't have it enabled before the backup
