Subject: CursesInfoPopup: separated the Curses popup widget from the rest of
 the UI code

 * this has been prepared a long time ago
 * the popup widget does not in any way depend on the InterfaceCurses
   class and could be used elsewhere.
 * common and generic Curses drawing functions required by both the
   Curses UI and the CursesInfoPopup widget have been factored out
   into curses-utils.cpp (namespace Curses)
 * this improved the UI-logic separation and helped in making
   interface-curses.cpp smaller
