Created an updater for updating the project with the latest emoji from emoji-cheat-sheet.com

This PR is an auto-updater script which will update the project with any new emoji from http://www.emoji-cheat-sheet.com.

I've included the script for doing the update as well as the latest emoji.

The script is written in bash and has been tested on OSX Mavericks, although there's no reason it shouldn't work on any other unix-like system.
