use interpreter event to display documentation in terminal and editor widgets * QTerminal.h, QTerminal.cc (QTerminal::doc_on_expression): Use interpreter_event to display doc browser instead of calling base_qobject::show_documentation_window. (QTerminal::interpreter_event): New signals. * command-widget.h, command-widget.cc (console::interpreter_event): New signals. (command_widget::command_widget): Forward console interpreter_event signals to command_widget interpreter_event signals. * octave-qscintilla.cc (octave_qscintilla::contextmenu_help_doc): Use interpreter_event to display doc browser instead of calling base_qobject::show_documentation_window. * octave-qobject.cc (base_qobject::terminal_widget): Also call connect_interpreter_events for QTerminal. * terminal-dock-widget.h, terminal-dock-widget.cc (terminal_dock_widget::interpreter_event): New signals. (terminal_dock_widget::terminal_dock_widget): Forward QTerminal interpreter_event signals to terminal_dock_widget interpreter_event signals.
