Render bold and emphasis as plain bold/italic

CHANGELOG.md

 - `adoc-goto-ref-label` (`C-c C-a`) now completes over the anchors defined in the buffer instead of asking you to type the id blind. It stays permissive, so an id that isn't defined yet can still be entered, and the cross-reference at point is still offered as the default.
 - The compilation error matcher now also recognises modern `asciidoctor:` diagnostics, not just the legacy AsciiDoc.py `asciidoc:` format, so jumping to warnings and errors works with current Asciidoctor output.
 - `[source,ocaml]` code blocks now fontify with `neocaml-mode` when it is available, falling back to `tuareg-mode` and then `caml-mode`. To support this, a value in `adoc-code-lang-modes` may now be either a single major mode or a list of candidate modes tried in order (the first defined one wins).
+- Bold and emphasized text now use plain `bold` / `italic` faces instead of tinting the text with `adoc-gen-face`. This matches `asciidoc-mode` (and the convention in `markdown-mode` / `org-mode`), so switching between the modes is less jarring. Customize `adoc-bold-face` / `adoc-emphasis-face` if you preferred the tint.
