- renamed ShowField* to ShowFieldType, ShowFieldContent, ShowFieldTypeAndContent, in order to reflect better what they do.
- by default, django_polymorphic's pretty printing of querysets/objects (via ShowField*) is not used anymore - ShowField mixins now also show the annotations (after the regular fields, prepended by "Ann:") - cleaned up implementation.fix_request_path_info
