Add ApplicationWindow::background

Convenient for setting a stylish background that covers the whole
window, that is, goes below the header and footer. The same already
works with Page, since it inherits Control.

    import QtQuick 2.6
    import Qt.labs.controls 1.0

    ApplicationWindow {
        visible: true
        width: 400; height: 400

        header: ToolBar { opacity: 0.5 }
        footer: ToolBar { opacity: 0.5 }

        background: Rectangle {
            gradient: Gradient {
                GradientStop { position: 0.0; color: "lightsalmon" }
                GradientStop { position: 1.0; color: "salmon" }
            }
        }
    }
