- Refactor authomatic-handler to enable adding identities. jensens

- Fix: use secret from settings as secret for Authomatic. jensens

- Renamed view ``authomatic-login`` to ``authomatic-handler``, because this
view will be used to add an identity too (url must be registered on provider
side sometimes and we want to do this only once). jensens

- Minimal validation of JSON. jensens

- Make the whole ``remember`` procedure a ``safeWrite`` if called from login
view. We can not pass a authenticator token here, because of redirects and
expected return urls . jensens

- Allow selection of user id generator strategy. jensens

- Allow multiple services for one user. This changes a lot behind the scenes. jensens

- Use authomatic.core.User attributes instead of raw provider data. closes [9](https://github.com/collective/pas.plugins.authomatic/issues/9) ericof
