Fix sync script :root parsing, add offline/editor/user to minify. Bump 03.10.06

- Sync: compare against standard theme (not deleted custom starters)
- Sync: handle :root{ on same line (dark.standard.css format)
- Minify: added offline.css, editor.css, a11y-high-contrast.css,
  user.css, user.js to minification list
