Add hyphens:auto to <p> to remove the ugly gaps introduced by
text-align: justified. This may cause some unwanted hyphenation on e.g.
email addresses. We should strive to not have long unbreakable words.
For record; command for adding html tag to all relevant files:
$ find -type f -exec sed -i '/DOCTYPE/ a <html lang="no">' {} +
