P2pool-vtc

This release introduces a second Vertcoin p2pool network designed for smaller miners, perhaps with only one or two GPUs who those do not mine frequently (ie miners are not running 24/7). The existing p2pool network has grown to be quite large, making it hard for smaller and infrequent miners to get a share. This new network can be accessed via the flag `--net vertcoin2`. Those who have dedicated VTC miners should continue to use the existing network.

This update activates SegWit on VTC testnet p2pool

This release fixes a bug where mined blocks did not contain a SegWit commitment

Note: this will fork the share chain

This is a hard fork of p2pool which implements the Vertcoin SegWit soft fork.
