Remove Shortcut from theme dependency

moved to NR as MR is provided

+1 to this request. I'm getting warnings that are resolved by uninstalling the Shortcut module (I identified Shortcut module menu items as what CT was choking on). However, there are further complications from removing a dependency of CT.

Warning: Undefined array key "url" in _civictheme_preprocess_menu_items() (line 40 of themes/contrib/civictheme/includes/menu.inc).
