Syntax highlighting

[Aloso]

For syntax highlighting, jekyll already parses the code and wraps tokens in spans with different CSS classes. All we need is some CSS to set the colors, e.g.

pre.highlight .k { /* keyword */
    color: #0b65ca;
}

I want to try minimal syntax highlighting, to keep with the low-color spirit of the website. We don't have a lot of code samples anyway, so just making keywords bold should be enough
