Changed to GENESIS_DEBUG from DEBUG
Changed to GENESIS_DEBUG from DEBUG

The amount of noise generated by Spruce when DEBUG env is set can make
it hard to see just the Genesis output.  -D will set GENESIS_DEBUG to
true internally.  Setting the DEBUG environment variable will also turn
on GENESIS_DEBUG if you want both output.
