(Bug 5161) Switch styleid to siteviews instead of user's style

* we do this if the user has in their preference to use site skinned
  comment pages, rather than custom comment pages
* old way was to return to the caller telling the caller to use bml, and
  have the caller call LJ::S2::make_journal again. But siteviews is s2
  anyway, so we might as well set the right variables and continue on
