Create a list of posts

* Instead of showing excerpts from each post, show a list of titles
* A list of titles is easier to navigate
Disable built-in code highlighting

* Continue using pretty print for now
Use javascript to prevent dots being cut off

* Dots in the background of an article list can be cut off by different
length article titles
* Use javascript and some modulus maths to prevent this
* A little tricksy because the length of the link changes when web
fonts load
Lowercase category names in posts

* Category URLs in Hexo are case sensitive
Update personal message

* No longer at Last.fm
* Now contracting at GDS
* Tweak article footer design since there are no comments any more
