Updated old post
Minor changes to stylesheet
Small fixes in footer, header and config.

Eliminated Rakefile from the output, updated copyright year (2012 - 2013) and
removed the "default" stylesheet from the header, because pygments' css is
concatenated to the css/screen.css.
Added 404 page and .htaccess file.

404 page made by copy-pasting the HTML code directly into a file. I'll make it so Jekyll creates the 404 page later -- it's basically some YAML Front Matter and half a dozen tags. But I'm too sleepy now for it.
