redirect stdout and stderr into experimental terminal widget
* command-widget.cc (command_widget): open temp files for redirecting
stdout and stderr, setup a file system watcher for signals on changes
to these files;
(~command_widget): close and remove the temp. files;
(insert_interpreter_output): use the style as second argument
(print_stream): add new contents of temp. files for stdout and stderr
to the end of the terminal contents;
(notice_settings): set the terminal preferences to the new lexer of
the console;
(console): create and set new lexer;
(new_command_line): use prompt style for the prompt;
(execute_command): use second command line argument for the style;
(append_string): use style as second argument and style the added
text accordingly;
* command-widget.h (console) append_string with second argument for style,
(command_widget): now with destructor, new method print_stream,
insert_interpreter_output with second argument for style, new class
variables for temp. file descriptors and file system watcher
* console-lexer.cc/h: new lexer derived from QScintillas default lexer
for styling the terminal output, styles used so far: Default, Error,
and Prompt
* gui-preferences-cs.h: new constants for error and prompt colors
* libgui/src/module.mk: new files console_lexer.cc/h
* qt-interpreter-events.cc (display_exception): interpreter_output_signal
with second argument for the style, here Error style
* qt-interpreter-events.h: interpreter_output_signal with second
argument for the style
* terminal-dock-widget.h: interpreter_output_signal with second
argument for the style
