the contents of the derived class widget.

When there is no other content for the InfoBox, show this
panel with the IB's description only.
Content/Base: add bool show_in_tab_layout

This property of the content allows the content to tell
its consumer whether it should be displayed in a tab
layout.

Set the show_in_tab_layout property to true for existing
tabbed content panels (Altitude, MacCready, Wind)
InfoBoxWindow: show either InfoBox Widget or Dialog

If a tabbed dialog panel exists, show it in the old static
dlgInfoBoxAccess, otherwise show the new fullscreen widget.
If no content exists, show just the description of the IB in
the widget.
Panel/Base: add NumberButtonLayout base class

This base class defines the layout for a widget that displays a value in
its center and two "up" buttons located above the value,
and two "down" buttons below the value.
It can be inherited by any class that wants to use this layout.

to adjust their MC setting to with respect to their final glide
altitude.  So, we display it on the widget.
List.cpp/hpp: add SetHasScrollBar(bool) method

If set to false, then the scroll bar is not drawn
for the list.

This will be used in certain dialogs used "in-flight"
that use "ratchet button" to navigate the list instead
of the scrollbar.
