Ralf Teusner d292fec47c Code Cleanup: Usage of Polymorphic User instead of ExternalUser and InternalUser
Renamed requestor_user_id -> user_id
Index of request_for_comments now returns the n (5?) newest requests per user. Solved via sliding windows in postgres, code added to model.
Added route to /my_request_for_comments/ that shows all requests for the current user.
Changed view from ERB to slim
