* Scinterm was simply rendering them as black, thus effectively
  breaking the Linux and FreeBSD vts with terminal.tes.
* I was considering to render light black as white on 8-color terminals,
  so it's always readable.
  However, if you add in A_BOLD there is a good chance that the
  color will end up grey - at least it does in the virtual terminals (consoles).
* There is no need to use bright colors in the Scintilla view defaults.
  E.g. 0xFFFFF is "light white".
  However on 8-color terminals this will be rendered like white anyway.
  The new defaults are closer to what terminal.tes does.

* Hopefully also fixed FreeBSD CI builds. Always define NCURSES_WIDECHAR.
* Windows builds were probably also broken.
  We now pass down PDC_WIDE and PDC_FORCE_UTF8 into Scinterm as well.

This requires a (yet unmerged) Scinterm patch.

The submodule has been reverted to its upstream URL.

* This is still rendered as underlined text.
* It uses a new Scinterm upstream feature, so we can
  switch back to the upstream repo.

* This currently needs a yet unmerged patch, fixing the light colors.
* Scinterm no longer systematically initializes the color pairs, so
  we cannot predict their numbers - instead we initialize color pairs
  on demand and store them in a hash map, very similar to what Scinterm
  does internally.
* Scinterm v5.5 can use arbitrary RGB colors now by automatically
  allocating curses colors and pairs.
  We do not expose this in SciTECO yet, although that would also
  be possible.
  It has to be decided first whether the special predefined colors
  will continue to live in the same namespace along with "true"
  RGB colors.

* The new official homepage is https://sciteco.fmsbw.de/
* My new contact address is rhaberkorn AT fmsbw.de.
* The scintilla-mirror is now also on https://git.fmsbw.de/scintilla-mirror/
* Added CI script for my server on fmsbw.de that builds
  the website.
  It's run in a FreeBSD container, but does not currently
  distribute FreeBSD binaries.

* SCI_COLOR_PAIR() is now a function teco_color_pair() since it also became
  an inline function in Scinterm.
