Rubocop config file now includes in execution

[jherrlin]

This will look for a config file in the project root and include it in the execution if found.

Is there any reason why this request doesn't get merged? Is it related to the naming of the rules file mentioned by @bbatsov ?

[bbatsov]

Yep.

There's also the fact that RuboCop would normally pick up the right configuration file anyways, as we're running it after cding to the appropriate directory. Generally I'm not quite certain what this PR was supposed to fix.

Guess that I didn't know that RuboCop picked up the configuration file or if I could not spell the config file name, dont remember. Should I close the PR?
