ES6 React UltiSnips snippets for vim

If you’re a React person and you use vim to edit files, and you use the UltiSnips plugin for inserting snippets, and you’re also using ES6 syntax to make those sweet, sweet React components you’ve got there, then you’re in luck because I just pushed some snippets to GitHub just for you!

The Readme links to the people originally responsible for the other snippets. I just enabled them for UltiSnips users too and updated them to the new ES6 syntax as recommended in the React docs.
