  Build static pages with Jekyll, like GitHub Pages does.
- Migrated systemd lexer.
  Thanks to Matěj Cepl.
- Migrated Lisp lexer and highlight character escapes.
  Thanks to Matěj Cepl.
- Migrated rpmspec lexer and made some improvements.
  Thanks to Matěj Cepl.
- Modernized reST lexer.
  Thanks to Matěj Cepl.
- Markdown lexer should just tag the start of a blockquote.
  The quote's contents may contain markdown.
- Output lexer can highlight CSI color sequences.
- Allow lexers to define their own fold functions.
- Added custom folder for Markdown headers.
- Added `lexer.line_start`, `lexer.line_end` and `lexer.text_range()`.
- Fixed Markdown lexer to not lex some continuation lines as code.
- Fixed SciTE not using Scintillua's markdown lexer.
- Markdown lexer should not highlight secondary paragraphs in list items as code blocks.
- Have SciTE recognize CMakeLists.txt.
