Skeleton for Express server framework and authentication.

-Includes framework for server.js file, which requires all necessary modules, configures server, and opens server.
-Updates package.json to include modules necessary for Express and Passport.
-Creates several new files (passport.js, auth.js, routes.js).  Passport and Auth will be used to handle authentication, while routes.js will eventually be used to handle all routes.
-Has several test routes that have no functionality in server.js.  These will eventually be removed and all routing will take place in app/routes.js.
