Deps on openssl cryptolib to compile

0a. Leave genesisblock.c to default to generate your own Block 0 hash

Set initial value of uint32_t startNonce = 2083236893 and uint32_t unixtime = 1231006505 in genesisblock.c
to generate original Bitcoin Block 0 hash

gcc genesisblock.c -o genesisgen -lcrypto

./genesisgen [PubKey] [TimeStamp] [nBits]

2a. ./genesisgen 04678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5f "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks" 486604799
