the command line macro is now managed by a Scintilla view

* Instead of rendering a teco_string_t into a Scintilla view (GTK)
  and an ncurses window (Curses), it is now a Scintilla view and document
  that is modified directly.
* Reduces redundancies between GTK and Curses UIs.
* It will be more efficient on very large command lines, especially on GTK.
* We can now redirect Scintilla messages to the command line view in order
  to configure syntax highlighting, the margin, rubout indicator style and
  scroll behavior (TODO).
* This will also simplify the configuration of multi-line command lines (TODO).
* Since INDIC_PLAIN is not supported by Scinterm, rubbed out command lines
  are now styled with INDIC_STRAIGHTBOX (background color).
