* This reference was added in the very distant past
* But jquery.history.js itself has never been in the repo
* pyconau-2017 team resolved the dilemma but dropping
jquery.history.js into the repo
* But as near as I can tell, this does nothing except in obsolete
older browsers. The fact that it's been broken ever since it was
"added" is highly suggestive of it never having ever been used or
needed
* So, trim the fat. It's possible that this might break an older
browser that needs the functionality jquery.history.js provides -
except that such a browser would *already* be broken because
jquery.history.js has never actually been around to be used.
* If we ever do need this functionality, we can revert this
change.. and then we'd have to drop in jquery.history.js. In that
circumstance,
https://github.com/pyconau2017/symposion/commit/34bc7c0 may be of interest.
