Replace Shadowbox with GLightbox, drop jQuery from public site

Vendors GLightbox 3.3.1 (MIT, dependency-free) as static files in
public/javascripts and public/stylesheets, replacing the Shadowbox
2009 vendor tree and its jQuery adapter. Public site no longer loads
jQuery at all.

- app/views/layouts/application.html.erb: swap Shadowbox script/style
  includes and the public_bundle (jQuery) include for GLightbox's
  CSS/JS
- app/views/content/_headline_image.html.erb: headline image is now
  itself a GLightbox trigger; additional images are direct
  a.glightbox links sharing a per-page data-gallery group, replacing
  the hidden shadowbox_images div and its click-forwarding trigger
- public/javascripts/public.js: replace Shadowbox.init/setup and the
  click-forwarding handler with a single GLightbox() init call;
  remove the unused image_handler object
- Remove public/javascripts/shadowbox/ (including vendored Sizzle,
  swfobject, and unused video/Flash players) and
  public/stylesheets/shadowbox.css
- Remove app/assets/javascripts/public_bundle.js (jquery require)
