Subject: added XCurses support

 * enabled via --with-interface=xcurses, so we can configure
   it automatically via xcurses-config.
   This also adds XCURSES_CFLAGS and XCURSES_LIBS.
 * The X11 window class name is set to "SciTECO".
   X11 resource overrides can currently not be set via
   sciteco's command line. The user may use .Xdefaults though.
 * interruptions via CTRL+C are currently not supported.
   Apparently, XCurses also does send SIGINT in cbreak() mode.
   An XCurses-specific hack would be cumbersome.
 * ~InterfaceCurses() should probably be rewritten.
   Curses cleanup should be completely in restore_batch() as
   the destructor may be called after Curses-cleanup handlers.
   E.g. isendwin() SEGFAULTs on XCurses when called from the
   destructor.
