implemented Scintilla lexer for SciTECO code, i.e. TECO syntax highlighting
* this works by embedding the SciTECO parser and driving it always (exclusively)
in parse-only mode.
* A new teco_state_t::style determines the Scintilla style for any character
accepted in the given state.
* Therefore, the SciTECO lexer is always 100% exact and corresponds to the current
SciTECO grammer - it does not have to be maintained separately.
There are a few exceptions and tweaks, though.
* The contents of curly-brace escapes (`@^Uq{...}`) are rendered as ordinary
code using a separate parser instance.
This can be disabled with the lexer.sciteco.macrodef property.
Unfortunately, SciTECO does not currently allow setting lexer properties (FIXME).
* Labels and comments are currently styled the same.
This could change in the future once we introduce real comments.
* Lexers are usually implemented in C++, but I did not want to draw in C++.
Especially not since we'd have to include parser.h and other SciTECO headers,
that really do not want to keep C++-compatible.
Instead, the lexer is implemented "in the container".
@ES/SCI_SETILEXER/sciteco/ is internally translated to SCI_SETILEXER(NULL)
and we get Scintilla notifications when styling the view becomes necessary.
This is then centrally forwarded to the teco_lexer_style() which
uses the ordinary teco_view_ssm() API for styling.
* Once the command line becomes a Scintilla view even on Curses,
we can enabled syntax highlighting of the command line macro.
