Add LaTeX style hyphenation about jonrh.is

[jonrh]

Added text-align: justify. It's okay but not great. I will leave this issue open to maybe implement a proper LaTeX style hyphenation. I think it might require some libraries though.

Noticed by chance while reading Cramming 'Papers, Please' Onto Phones that the site was using hyphenations:

.content p {
  hyphens: auto;
  -moz-hyphens: auto;
  -ms-hyphens: auto;
  -webkit-hyphens: auto;
}

According to caniuse.com hyphens have 97% support with vendor prefixes and 78% unprefixed. For hyphens to work the HTML lang attribute must be specified which it already is. Support is lackluster for many languages but since this website is only in English it should work. Worth trying out at least.
