Changing yamler to syck

[mmb]

Updating to the latest rubocop in my rails app broke delayed_job by switching the YAML::ENGINE.yamler to syck.

Granted I'm using an older 1.9.3 version of ruby but could the empty yaml problem be handled in a way other than globally setting the yamler to the old broken one? It seems like this might cause some unexpected issues.

Yes, that's probably a good idea. I didn't consider other applications using RuboCop as a library when I implemented the fix for the empty YAML file problem. I'll try to sort it out.
