Config debug flags are now represented as individual items, eg: servald config set debug.verbose yes servald config set debug.rhizome yes instead of aggregated, eg: servald config set debug verbose,rhizome <-- no longer works Added a debug flag "debug.all" that can be set and cleared, over which individual flag sets/clears take priority. Slimmed down dna.c by moving some globals and functions to the files where they are used. Default command line (help message) is now the new style, not the deprecated style.
