Commit summary:

Use FileAPI for previews when possible.
This complicates the situation of when a thumbnail may be generated. Depending 
on config or layout, it could be any of:

1) Thumbnail wanted before ready
2) Thumbnail wanted after ready

multiplied by

1) FileAPI, locally scaled
2) Stashed Image API, remotely scaled, with exponential backoff retries
3) Image API, remotely scaled, with exponential backoff retries

And of course all the error conditions!

So, I have moved to a different model for obtaining thumbnails, where you just 
declare that a certain HTML element needs a thumbnail with
setThumbnail(), and the framework figures out what it's supposed to do, and the 
thumbnail should show up eventually (or finally
give you a broken image and an error condition).

The thumbnail framework is now using a pub/sub model with a twist; certain 
events can happen only once, and you can subscribe to them
in the past. This is a little bit like the 'ready' state of some DOM elements, 
so these are called by 'publishReady' and 'subscribeReady'.
Think of it as "publish that we are now ready to show this thumbnail" or "do 
this action when the thumbnail is ready (or right away if
it already is)".
