Title: Oxford Comma Support

Per #1, added the ability to use the existing API to support [Oxford commas][1].

This is achieved by simply checking if the supplied conjunction (e.g. `and`) is preceded by the separator (e.g. `, `), such as `, and`. When true and there are fewer than 3 elements, the separator is sliced off.

- Created tests
- Modified `join` to support Oxford comma
- Updated README via `mocha --reporter markdown test/index.js`
