move the unit testing log4j.properties out the 'test' code folder because then it's also used in a lot of other places.  instead just create a new test_resources folder which we only apply to the unit tests profile.

we don't need to manually make log4j changes in code, we can have a log4j.properties file specific to unit tests instead.

fix up logging config so that it's useful and defaults to printing to stdout.  use logging calls instead of printlns.
