@florianeckerstorfer Give me a note, if you prefer squashed commits.

Hi
Thanks a lot for your help. But I think I made a mistake when I choose your post.
Have a nice day

@florianeckerstorfer I believe this can be closed now that #382 has been merged. :)

PS- Unless you prefer to change the minimum required version of Symfony to 2.7.
