React Leaderboard

Meteor's leaderboard example app, rewritten in React.

Notes:

Make sure you update submodules after checkout to get our extended webapp + react-meteor packages, submodule update --remote --init

1. Our forked version of the webapp package allows server-side rendering.

This change is currently in consideration for Meteor core (meteor/meteor#3860)

2. Our fork of https://github.com/reactjs/react-meteor works with Meteor 1.0.3.2.
