Based on the original blog theme by James Doyle:
https://github.com/PhileCMS/Phile-Blog-Theme/

Features/changes:

* All CSS in one file
* Understated colour scheme
  - Dark blue/black on white
  - Light grey code blocks with more modern fonts (no syntax highlighting)
  - Hyperlinks use alternating dark blue/black colour scheme
* Static links in the navigation code (instead of dynamically generated ones
  in the original blog theme)
* Template for blog content:
  - Last updated date displayed (only if set)
  - Article title is not clickable on article page itself (useless when
    reading the article itself)
* Template for static content:
  - Page title not shown on page itself
  - No date shown; last updated date displayed at the bottom (only if set)
* Added bottom border for all content (not just blog posts)
