Change Details

As described. Having a check point on fork block means nodes cannot be led onto wrong UAHF-compatible chain. Knowing that you are on right Bitcoin Cash chain after the fork block can be used to optimize some code which determines whether we are pre-fork or post-fork.

Changes to chain params: - added fork block checkpoints for mainnet and testnet3 - update defaultAssumeValid for both chains - updated nMinimumChainWork to match the defaultAssumeValid blocks Having a check point on fork block means nodes cannot be led onto wrong UAHF-compatible chain.
