Fixed unittest failure, cleaned up unit test output

- Fixed unittest failure in LogLevelTest (and improved tests)
- Added config dir with logback config file that set logging to stdout and level to Error.
- Modified unittest target used by travis-ci to use new logback config file to reduce clutter in unittest output.  
- Commented out superfluous System.println's from various unit tests to also reduce clutter.

Also, eclipse reformated some of the lines to match code style.
