GLightbox's own selector-based description feature never actually
resolved a selector in three different attempts -- literal text,
then a resolved-but-empty div, then apparently not firing at all
against the installed (unversioned) build. Replaced with a small
afterSlideLoad handler that reads a plain data-credit-selector
attribute and copies the real element's HTML into the slide's
description area directly, depending only on GLightbox handing back
a real DOM node per slide -- a much smaller contract than trusting
its own caption-resolution feature.
Renamed the credit div's class from glightbox-desc, since that name
is reserved by the library's own bundled CSS (display: none
!important) and can't be reliably overridden from here.
Also: distinguishes the credit line and the "N Bilder" caption from
ordinary body text (italic, muted, matching .author_and_date's
existing convention), and makes the lightbox's caption card follow
the site's light/dark toggle via Canvas/CanvasText, since the
library's bundled theme never adapts to it on its own.

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)
