Updates package.json

Hi Semmy,

I've updated the package.json file with the dependencies and removed the node_modules folder.  I tested from scratch to make sure that it worked when cloning the repo, running npm install, and then starting the server.  

Please note that the Redis dependency is set to v0.7.1 purposefully.  When I set it to install the newest version (v0.7.3), it breaks.

Thanks!
Danielle
