+Subject: [PATCH] Introduce PlaceholderMessage
+
+This is a clone of the Kirigami component that we can use in Plasma
+applets until we arrive at a solution for styling QQC2 items using the
+Plasma style (https://phabricator.kde.org/T13256).

++/**
++ * A placeholder message indicating that a list view is empty. The message
++ * comprises a label with lightened text, an optional icon above the text, and
++ * an optional button below the text which can be used to easily show the user
++ * what to do next to add content to the view.
++ *
++ * The top-level component is a ColumnLayout, so additional components items can
++ * simply be added as child items and they will be positioned sanely.
++ *
++ * Example usage:
