Title: Add a more general purpose "merge" method.

If we have a "merge" method, it fully duplicates the functionality presented in https://github.com/Wolfy87/Heir/pull/4, but in a much nicer way.

I also added `heir.hasOwn`, as a shortcut for `Object.prototype.hasOwnProperty`. The "why"s for that are explained in the method's DocBlock.
