CHANGELOG: Changing the "Show icons in menus" setting will now immediately be applied to running applications
Changed the "Show icons in menus" settings and menu immediately lost all its menu icons. Enabling the setting brought them back.
Follow-up patch will remove the notification about how this applies only to newly started applications.
If I do removeKey("ShowIconsInMenu") rather than explicitly setting it
then call settings changed, this will always remain on whatever it was before; rather than matching what the actual default should be.
