Enable AllowComments for Style/EmptyElse ?

[andyw8]

As discussed with @paracycle and @Morriar.

By default RuboCop will not allow an empty else, or an else with only a nil.

But in some cases, having an empty else clause can help communicate the intent, even if the else isn't returning anything.

if foo
  bar
else
  nil
end

Isn't idiomatic Ruby. In ruby empty elses aren't necessary

After second thought, let's do it.
