Integrate more automated testing

[mariobehling]

We already have travis and code climate. I wonder, if it would be good to see if we can get more data and automatic comments about our code like what houndci does for example (for other languages). What options do we have for php? Please check and evaluate, which ones are most suitable for this project.

nitpick-ci is successfully integrated into the repository. It'll now automatically check for PSR-2 coding style. Refer to the PSR-2 coding style here, http://www.php-fig.org/psr/psr-2/

I am currently working on integrating codacy for this repository.
