Add configurable support for angled quotes
The flag `HTML_SMARTYPANTS_ANGLED_QUOTES` was added to Blackfriday on Black Friday. This configures rendering of double quotes as angled left and right quotes (« »). Typical use cases would be either or, or combined, but never in the same document. As an example would be a person from Norway; he has a blog in both English and Norwegian (his native tongue); he would then configure Blackfriday to use angled quotes for the Norwegian section, but keep them as reqular double quotes for the English. This commit adds configuration support for this new flag, configuration that can be set in the site configuration, but overridden in page front matter. Fixes #605
