Changed the name, it is not a PopupMenuController, but a ToolbarController that
shows a PopupMenu filled at runtime by a PopupMenuController

Make it a base class for other ToolbarController components, there is no sense
to make it a component by itself

Use this base class for three new pure UNO ToolbarController's
