Add smartDashes flag for Blackfriday

To allow the end users to disable any form of smart dashes
(LaTeX-style or not) while keeping the rest of Blackfriday
SmartyPants features.

Depends on https://github.com/russross/blackfriday/pull/190
"Add HTML_SMARTYPANTS_DASHES for toggling smart dashes"
to be accepted by Blackfriday developers.
