Migrate visual design to align with ACCD web properties

This brings the theme styles in-line with the Planning section of the ACC website.

Apply page Order values directly to subsection ordering

Before:

index.md
---
order: 1
---

Now:

index.md
---
order: 0
---

This allows the actual .x subsection value to map directly to what's defined in the front-matter. In this case, index.md represents the home page of the parent Section, and then the first subsection would have order: 1 defined.

Initial design consideration

This incorporates the initial actual design, and introduces the following config-based changes:

• Random background generator: Specify a number of background photos (integer 1-n) as a random_background_images configuration, then place any number of files n.jpg in assets/images/backgrounds/

• Parent Site support: Add a link atop the navigation to a parent site, in our primary case either ACC or PEC production sites when viewing the respective ops policy site. The theme will look for the logo file in assets/images/

parent_site:
  title: Austin Convention Center
  url: https://www.austinconventioncenter.com
  logo: "acc-logo.jpg"
