Title: Add option to control displaying categories on menu 

This option is DISPLAY_CATEGORIES_ON_MENU and controls, in both default themes, whether categories get displayed or not on the menu. I see this as being most useful in situations where one only wants a set listing of pages in the top menu and no categories at all.

This option is enabled by default, meaning a default install remains the same for backwards compatibility.
