Replace Atom::getLoadSettings with a ::loadSettings property

We assign a value into ::loadSettings anyway in a spec, so there's not
much point leaving it a method. Eventually I'd like to pass all these
settings in when constructing the Atom object and eliminate awareness
of the loadSettings altogether from the Atom global.
