Title: Close #576, Close #573, Close #571, Close #570

This commit uses feature detection with MultiJson so we don't have
to lock to specific version which would impact other projects.

The commit also handles the edge case where OkJson is loaded
and may be referenced in an unknown namspace.

Idea: https://github.com/jonleighton/poltergeist/pull/52/files
