docs: Determines whether or not user info should be retrieved. This
   allows some strategies to save a call to an external API service
   for existing users. You can use it either by setting the `:skip_info`
   to true or by setting `:skip_info` to a Proc that takes a uid and
   evaluates to true when you would like to skip info.
  
   @example
  
     use MyStrategy, :skip_info => lambda{|uid| User.find_by_uid(uid)}
