feat: one breadcrumb, same place and style on every inner page

- Plugin: vc_breadcrumb_trail()/vc_breadcrumb_html(); tours, region, city
  and tag pages show Home / (Region) / Page in the banner instead of the
  generic 'Tour & Travel' label; the tour page uses the same helper
- Theme: blog list shows Home / Blog; blog post title, breadcrumb and
  meta move into the banner like the other pages
- Shared style: title's colour (white in photo banners, black on About),
  softer links, current page bold and shortened if long - also on phones
- Plugin 1.9.6, theme 1.0.16
