Added a first cut at using Prismatic Schema for validating, defaulting and converting user specified config
Added a bunch of schema tests, moved more config from config.clj over to
schema, more defaulting from jdbc.clj
Added Prismatic style pragmas and an ns level doc string
Removed an old commandproc config function
Move more connection pool config out of jdbc.clj and into
config.clj (using Schema)
Updated docstrings to clarify args, renamed convert-ini-map-config fn in config.clj
