Custom fields in `service_user_info`

[hkdobrev]

In Auth_Service_Facebook::service_user_info() the user info is requested via the /me endpoint.

It would be useful to define custom fields in the configuration.

For example:

/me?fields=id,name,email,username,installed,work

The advantages of specifying fields are:

• Adding fields which are accessible only when specified in the fields parameter. Such fields are:
  • installed
  • security_settings
  • third_party_id
  • cover
  • currency
  • picture
  • video_upload_limits
• Limiting the response to the needed information only so it could be faster. If a user has exposed a lot of information to the public, /me would have a very large response.

The only way now is either use a separate request or extend the class Kohana_Auth_Service_Facebook and override the method.
