genesisgen

Genesis block generator

This program is based on "Remember remember the 5th of November"'s post [ANN] Genesis Block Generator with some improvements.

• Add a Makefile
• Add command line arguments for startNonce and unixtime
• If timestamp string is longer than 76 bytes, add OP_PUSHDATA1(0x4c) to scriptSig.
