Feature/unit tests (#64)

- fixed unit tests on Windows. We will adapt them for other platforms as well.
  nntp and postprocessor tests do not pass. We will debug them later.
- separated the tests from the application itself
- using CMake to configure files for building tests. We will completely switch to CMake later.
- deleted obsolete Autotools generated files
- updated README
