Fix tests with latest versions of smartypants.

smartypants is now py3 compatible but the default settings for double quotes has
been changed (http://pythonhosted.org/smartypants/changes.html).

This commit:
- update the typogrify test (change quotes, and add more test casesi: caps word,
  ellipsis)
- install typogrify on travis
- uses upstream version of smartypants in tox instead of dmdm's fork for py3
