Subject: 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)

-A Shadowbox "player" is a class that is used specifically for displaying a
-particular medium. For example, an image player is included for displaying
-images, a QuickTime player is included for playing QuickTime movies, etc.
-
-All players should implement the same interface. This makes it possible for the
-Shadowbox class to know what methods to call and properties to check on player
-objects.
-
-The interface is described here, with some simple explanations of how each
-method and/or property is to be used.
-
-METHOD/PROPERTY     DESCRIPTION
-
-height              (Number) The height of the object (in pixels)
-width               (Number) The width of the object (in pixels)
-ready               (optional, Boolean) True if the content is ready to be
-                    loaded, false otherwise. Useful when the script should wait
-                    until the content loads before proceeding (see below)
-resizable           (optional, Boolean) True if the content can be dynamically
-                    resized by the script (e.g. images, but not most movie
-                    formats)
-append()            Appends this object to the DOM
-remove()            Removes this object from the DOM
-onLoad()            (optional) Called after the content is loaded and the
-                    loading layer is hidden
-onWindowResize()    (optional) Called when the window is resized
-
-If the ready property is set to false, the script will wait until it is set true
-before proceeding to call the onReady callback. This property should be changed
-in some callback function within the player class itself.
-
-In this case, the object's height and width do not need to be made available
-immediately (because they may not initially be known). However, in the same
-callback, the height and width should be set. See the Shadowbox.img class (in
-shadowbox-img.js) for an example of this behavior.
