Add note about missing 'login' and 'logout' event
BIG REFACTORING : read the commit message

- Everything is a service (apart from hullShare data)
- 2-way data-binding setup, and mostly works (see my question on SO http://stackoverflow.com/questions/20881217/data-binding-from-external-http-api-wrapped-in-a-service-does-not-work/)
- Login button doesn't work though
- In general code is way better, and more "Angular-ish"
