Update All the Modules

[tlhunter]

Need to run npm update in the root to get everything to the most recent version.

• Express 3
• Mongo is old
• Socket.io is old too

Delete the mongo package, since we use mongodb.

Make sure the output of npm ls contains no errors.

Update all of the code in server.js which breaks due to the new packages. Socket.io, Mongo, and Express all go nuts.

Get a list of the packages that get installed, and add them to package.json. Then, delete everything within the node_modules directory, and add that to .gitignore. In the README.md file we should say that after the files are checked out, one needs to run npm update to get the latest files.
