support "default colors"HEADmaster-fmsbw-cimaster

* The terminal's default foreground and background colors
  are now used by default (`sciteco --no-profile`), so SciTECO
  integrates naturally into all terminal color schemes, even
  dark-on-bright ones.
* The default Scintilla colors use only 0x000000 (COLOR_BLACK) and 0xC0C0C0 (COLOR_WHITE)
  now.
* You can use `7EJ` to configure the default colors in color
  schemes or your profile.
  All existing color schemes had to disable default colors
  (`-1,-1,7EJ`) since they wouldn't look well otherwise.
* You may add `-1,7EJ` to ~/.teco_ini when using a terminal emulator
  with a washed-out palettized COLOR_BLACK.
  We cannot detect the terminal's default colors automatically.
* Scinterm updated to v6.0.
  We require a not-yet-upstreamed patch:
  https://github.com/orbitalquark/scinterm/pull/40
* In fact, we might decide not to support default colors at all in Scinterm,
  so this feature should be considered experimental.

    We'd have to handle an overlapping info popup, though.
    Should we deactivate the hardware cursor via curs_set(0) if it overlaps
    the popup?
- * ncurses: Support default colors (use_default_colors()).
-   Instead of drawing a black background and white foreground
-   we could use pair number -1.
-   This means you don't suddenly become white-on-black on terminals
-   that use black-on-white by default.
-   On the other hand, not all color schemes might look good,
-   so this would have to be a setting (ED flag).
-   Also, Scinterm would have to support it as well.
-   This also appears to be responsible for the greyish background
-   on Haiku and GNOME Terminal: They don't have a true black as color 0
-   even if the default terminal background is a true black.
  * Ctags support
    Perhaps can be Video TECO compatible.
