I'm used to double quotes and it seems like other strings were left as double quotes?  Let's choose whatever is most common for the Ruby community and stick with it.

Rubocop changed these around from the double quotes I did because it says single quotes should always be used unless you need the #{var} interpolation feature, which is only available on double quotes.

I've seen similar rules in PHP for the same reason, the interpreters allegedly slow down to scan for interpolated values. Personally, meh I'd prefer to just use the double quotes everywhere, but this was a rubocop rule that was pretty easy to do so I went with the flow.
