function admin_menu_menu in Administration menu 5.3

Same name and namespace in other branches

1. 8.3 admin_menu.module \admin_menu_menu()
2. 5 admin_menu.module \admin_menu_menu()
3. 5.2 admin_menu.module \admin_menu_menu()
4. 6.3 admin_menu.module \admin_menu_menu()
5. 6 admin_menu.module \admin_menu_menu()
6. 7.3 admin_menu.module \admin_menu_menu()

Implementation of hook_menu().

We can't move this into admin_menu_footer(), because PHP-only based themes like chameleon load and output scripts and stylesheets in front of theme_closure(), so we ensure Admin menu's styles and scripts are loaded on all pages via hook_menu().
