Change handling of starred/default images

- EC2 has hundreds of images, we keep a list of 'defaults'.
- The rest providers only offer a handfull, so we consider all of
  them to be 'default'
- The user sees an image as starred if he has starred previously
  starred it or if it is a default. The user can unstar an starred
  or default image.
- For the user, a 'default' image is simply an image starred by
  default.
- For the backend, default and starred aren't the same, one is
  hardcoded in config.py, the other saved per backend in the db/yaml.
