I have pushed some new code into 1mb_segwit. Changes:

• Initial support for Bitcoin Cash. Use --net bitcoincash at the command line. Please let me know if you plan on running a BCH node with high uptime so I can add you to the DNS seeds list.
• Compatible with bitcoind pruning. Set "prune=10000" in your bitcoin.conf to limit it to 10 GB of disk space used for block storage (plus around 5 GB for the UTXO database)
• Improved block size and weight checking to avoid invalid blocks caused by the coinbase transaction putting the block over 4 million weight. Shares that exceed the block size or weight limits will be punished (i.e. orphaned).
• Minor CPU usage improvements by caching deserialized and unhexlified transactions when performing getblocktemplate calls
