properly stopping phantom process after tests
removed imageAddAttribute's dependency on loRes option

turns out it always needs to output a lower image resolution (because
the images get brought down to that size when they get shrunk anyway)

  pagination stage
- fixed incorrectly named "style" option (should've been "css")
- added cleaning up phantom at the end of running apocalism.js
- added temporary fix for the following typogrify bug:
