Clean up layout files
Adding live chat page
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 Removed outdated `navi.css`.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
