Explanation
- You can view the entire list of built-in stock images at here. What we are doing here is to check if the menu name has a corresponding built-in stock images. First we need to remove all "_", then replace all <space> with "_", then add "Gtk::STOCK_" in front of the string.
- Then we check if such constant exists. If yes, we construct the menu using GtkImagemenuitem. If no, we use the standard GtkMenuitem
