Title: Add object/deepMixIn

This adds a method that works like jQuery's [extend](http://api.jquery.com/jQuery.extend/) method with the first parameter `true` to specify the deep copy.

Not totally sure about the name, it could be a mutating `object/merge` or a deep copying `object/mixIn` method. It is closest to `object/mixIn` in the code, though.
