• core/html_api.php
  (print_menu_graph): use config_api to get options and use icon_path option instead of hard-coded 'images/'. I haven't tested this change because I don't have jpgraph but it was a simple change.

• print_all_bug_page.php
  use icon_path config option instead of hard-coded 'images/' and create four icons by looping and echoing rather than by duplicating html with lots of inserted php tags

Thanks to Ondrej Jombik nepto@pobox.sk for catching the 'images/' problem
