Apply Eclipse source formatter

- it is not a perfect win, but since much of the code was strangely formatted it is overall better
- and we only loose a minimal history for the blame view anyway...

Added a JUnit Test for proper Testing inside Eclipse

- added a hack to avoid SOM calling system.exit during tests
- should be solved properly with an exception for instance, or SOM exception support (I also have a SOM version of SUnit that could benefit from exception support)
