When the lightbox is opened, or prev/next pressed, preloads the
previous/next N images.
Technical debt introduced:
* initialization is a mess, with the viewer and the interface
randomly setting properties on each other in different phases of
execution. That got in the way and I shuffled things around
until they worked, which is obviously not the way to have a
robust system, but hopefully it will get scrapped soon anyway
in favor of a clean top-down dependency injection.

A simple task queue which can be processed or cancelled.
Will be used to handle preloading in a more robust way.

* moves generic logic into ThumbnailSizeCalculator class
* moves UI-specific logic into interface class
* fixes bug where non-bucketed sizes were served on devices with
non-standard pixel density
* fixes bug where bucketed size was compared to css size instead of screen size
for resizing

Interface code is its own class which does not depend on the main
interface class it can be unit tested (and eventually moved into its
own file to make browsing the code easier). IMO we should aim to
eventually break up the interface into similar classes (with a simple
init/empty/set interface + custom events where it makes sense).
Also, sneak-introducing LESS!
API usage could be more effective (globalusage is a separate API call;
it needn't be), but we will have to rewrite that part soon anyway, so
it should pass for now.
