Programmatically setting html_translator_class is apparently broken in
Sphinx 1.5 (which sorta makes sense, it's a bit of a hack, I'm not sure
why we even did that instead of going through the configuration object).
app.add_node doesn't work right for custom translators in 1.2, since
mementos are using ``h:div`` reimplement that in the
BootstrapTranslator.
Alternative would be to monkeypatch app.add_node for Sphinx 1.2, but
let's not do that...
Sphinx.set_translator is a Sphinx 1.3 API, and we only require Sphinx
1.2 at this point. Replace the use of set_translator with explicitly
setting the html_translator_class config setting.
