Cleanup api

[ivarconr]

(Still WIP)

• Clean up the express code
  • All routes in separate folder
  • All db-code in separate folder
  • All config set up in one place, use nconfig or similar
  • All required config injected to routes (database abstraction injected from top)
  • initialize all stateful modules at top and inject (this will ease unit-testing)
• Upgrade to Node 6 Node 5
  • pending pg issue: Doesn't work under Node.js 6.0.0 brianc/node-postgres#1000
  • upgrade project
  • [ ] upgrade docker to node 6 (do this in separate branch)
• upgrade all libraries to latest version
  • This does not include frontend-dep such as react, redux.
• serve favicon
