On some platforms (i.e. Firefox for Windows), the scrollbar was shown
regardless of whether it was necessary.

Fix cgit CSS

Fix whitespace throughout

Fix selectors for table row highlighting

Fix commit message formatting

Complete rewrite of cgit CSS

Refactoring more whitespace

Adding resources not yet in use on public site

Reworked CSS

Refactor head partial

Switch commented-out resources to conditional resources. Now these CSS
and JS files can be sourced on a per-page basis. Simply set e.g.
`lightbox = true` in the header of a Markdown file.

Removed outdated `navi.css`.

Added helpful comments and reorganized resources by type rather than
source.

Added logic to JS inline script so that the list navigation can be
tabbed through and the focused item will trigger on hitting Enter.

New post and redid some styling/templating

Migrating hosts; Remove old JS
