disable experimental terminal widget when building without qscintilla
* command-widget.cc: inlcude into #if defined (HAVE_QSCINTILLA)
* main-window.cc: include command-widget.h only if HAVE_QSCINTILLA
* module.mk: only build moc-command-widget.cc if HAVE_QSCINTILLA
* octave-qobject.cc: include command-widget.h only if HAVE_QSCINTILLA,
(base_qobject::terminal_widget): use conditional compilation where
referring to new terminal widget
* terminal-dock-widget.cc: include command-widget.h only if HAVE_QSCINTILLA,
(terminal_dock_widget, init_command_prompt): use conditional compilation
where referring to new terminal widget
* terminal-dock-widget.h: use conditional compilation where referring to
new terminal widget Thu Sep 01 02:34:37 2022 +0200
* octave.cc (cmdline_options): only return true on experimental terminal
widget option if built with scintilla
