Restructured application in prep of adding on blogging capabilities to the site.  Postgres dependency added on.  Application setup broken out into configApp.js.  Next step: extract a lot of the anonymous functions into the routes.  Break up the routes.
Moved configApp.js out of lib.  Not really reusable.
Refactored routing.  Moved prod/stage error handler into own file.
Forgot index.js in last commit.
