Genesis Block Generator for Blake coins

This version generates a 150 coin block reward, not a 50 coin block reward.

The Blake hashing is included and does not need any link libraries; only openssl development libraries are needed. On Unix like systems, e.g. sudo apt install openssl-dev or sudo dnf install openssl-devel.

See transaction->outValue = 150*COIN; in InitTransaction, line 127. Change to 50*COIN for Bitcoin-like coins.
