// The menu bar: who this is, what is not a zone, and whether the server is
// there.
//
// v4's arrangement, and the reason an app with only zones reads as unfinished:
// a zone head holds what acts on THAT zone, so anything that acts on the app --
// a window, a preference, the state of the connection -- has nowhere to live
// unless there is a bar that belongs to the app itself.
//
// Only menus with something real in them exist. An empty File menu is a promise
// the app does not keep, and this project's rule for an inapplicable feature is
// that it is absent rather than greyed.
