RAT-180: Generify RAT report

* Changed format of plain-rat.xsl (wording and spacing).
* Enhanced Resources helper class to be able to load from src/test/resources
  and src/main/resources. Unfortunately resource loading in tests does not
  work from within IntelliJ since it has a different current working directory -
  adapted Resources helper to work from the command line.
* Refactored tests to use Resources-helper to load any test/main resources,
  adapted test expectations.
