Grumphp.yml not getting created

As written in #3 :

I expected a new grumphp.yml to automatically appear beside the original one, but by some reason it did not happen.

I tried it according to the updated README and I found the following:

• phpcs.xml gets created as expected
• grumphp creates its own, default grumphp.yml file preventing our version from getting created

Proposed solutions:

• We could somehow force our package to run the install scripts before the ones in grumphp get called (is this even possible? composer hooks need to be researched more)
• We should simply try to create grumphp.yml (as we do now) if that fails or there's one already there, create a grumphp.dev-tools.yml and write about it the console.
