Emoji extended

This contains two new versions, one for 0.5.4, and one for 0.6.0, make sure you publish them both:

``` bash
$ git checkout 1cb3c68
$ npm publish
$ git checkout master
$ npm publish
```

Also two notes:
1. I have no idea why `package.json` got changed to 4-space indents, feel free to change it back
1. I still don't compile coffee, so please test to make sure I didn't break anything :smile:
