- /authenticate/:provider routes can now receive a 'redirectTo' parameter. This is where the user is redirected
  after succesful authentication (if used overrides the url set in OriginalUrl by SecuredAction)
- ProviderController.authenticate signature changed. Breaks compatibility: routes file needs to be adjusted (see sample apps)
- Added support for linking accounts. New 'link' method in UserService needs to be implemented.

- Small fixes for NL messages (thanks @francisdb)
- Added German translation (thanks @l0rdn1kk0n)
