kicker: add option to make root level icons visible
Summary:
In file applets/kicker/package/contents/config/main.xml an option 'showIconsRootLevel' is mentioned. It has following description:
"Whether to show icons on the root level of the menu."
This change provides implementation for this option.
Test Plan:
Manual test:
- Change menu to 'classic menu' (kicker), notice root level menu items have no icons
- Open menu settings widget
- Notice new checkbox 'Show icons on the root level of the menu'
- Check that checkbox and hit 'Apply' button
- Root menu items should now have icons similar which look similar to icons in 'modern menu' (kickoff)
