Make num_food_consumed right-aligned.
Add Minister of Food to Ministers menu.  Rename Minister of Happiness to Minister of Morale and add a function.  Set up MENU_MINISTERS in Interface::do_menu_action() and fix MENU_BUILDINGS.  Some changes to Interface::minister_food(), most notably colorization of number fields.
New function, Interface::minister_morale().
Comment out call to check_world_resources() - they look good enough that we don't need to check them every time.
Improve progress popups.
