Passport testing:
- Use express 4.0.0 because Passport is really not supported outside of express
- package.json, add development dependencies for express 4.0:
  - morgan
  - cookie-parser
  - body-parser (not sure that we actually need this one for theses tests)
- test/http.js: use express instead of connect
- test/passport.js; use express instead of connect, WIP
