Small bundle of changes

- Changes in config file reading method (old was not working for me at all)
- Removed file filtering for stash (filtering should be done globally)
- Fixed PMD
- Added jacoco + coveralls (badge needs to be changed to right one after pull)
- Few other small fixes
That line needs to be changed after merge to reflect owner directory..

And if you dont have you need to make free account on coveralls.io
