Skeleton switched from having 16 columns to 12. A few improvements to
skeleton also required a little tweaking of the current css as well as a
cleanup of templates/default.html.
Note: templates/default-nojs.html was not updated though an update will
be trivial. This is only relevant if the nojs section of the site is
revived.
