Make figures look a bit nicer.

Fix update content not being markdowned, improve style of
update blocks.

Show pointer cursor hovering over the contact summary.

Remove picture from the hire me bit.

Thanks Shane.

Split the build up into multiple stages:

 1) Hugo
 2) Minfy
 3) Serve

This means nginx is serving instead of hugo, and there are
no random apps installed in the end container.

text-decoration-skip is supported by Chrome now, hopefully
other browsers will follow suit...
