Deadwood snapshot update

I have begun work on having proper log levels in Deadwood. I added a verbose_level Deadwood parameter today and have started work on converting raw printf statements in to calls to a logger that sees if the message in question is one we show at the user-selected verbose_level.

This work will continue tomorrow or later this week; there are a number of printf statements I need to evaluate in the code.

The snapshot is in the usual place.
