* feedback_get_courses_from_sitecourse_map() now returns course id as 'id' attribute
* Base class for feedback items - feedback_item_base - has been significantly changed, all item types now
  must implement method complete_form_element() instead of print_item_preview(), print_item_complete(),
  print_item_show_value(), check_values(), clean_input_value() and value_is_array(). Rendering the items
  on complete form, feedback preview, feedback edit and when viewing response is done using moodleform.

  * feedback_print_item_preview()
  * feedback_print_item_complete()
  * feedback_print_item_show_value
  * feedback_check_values()
  * feedback_clean_input_value()
  * feedback_get_context()
  * feedback_create_item()
  * feedback_set_tmp_values()
  * feedback_delete_completedtmp()
  * feedback_get_page_to_continue()
