Gilles Dubuc 28b8f5095e Use cross-origin img attribute instead of data URI
After lots of experimenting with Wireshark and
current Chrome + Firefox on Ubuntu 13.10, this is my
current understanding of the caching when preloading images
with AJAX requests:

* on Chrome, the image request always comes from browser cache
* Firefox makes two separate requests by default
* Firefox with img.crossOrigin = 'anonymous' makes two separate
  requests, but the second one is a 304 (does not load the
  image twice)
* when the image has already been cached by the browser (but not in
  this session), Chrome skips both requests; Firefox skips the AJAX
  request, but sends the normal one, and it returns with 304.

"wish I knew this when I started" things:
* the Chrome DevTools has an option to disable cache. When this is
  enabled, requests in the same document context still come from
  cache (so if I load the page, fire an AJAX request, then without
  reloading the page, fire an AJAX request to the same URL, then the
  second request will be cached), but an AJAX request - image request
  pair is an exception from this.
* when using Ctrl-F5 in Firefox, requests on that page will never hit
  the cache (even AJAX request fired after user activity; even if
  two identical requests follow each other). When using clear cache
  + normal reload, this is not the case.
* if the image does not have an Allow-Origin header and is loaded
  with crossOrigin=true, Firefox will refuse to load it. Chrome will
  log an error in the console saying it refused to load it, but will
  actually load it.
* Wireshark rocks.

Aaron Arcos 8a1bf00ef0 Remove fire_event("onfocus") from next/previous/exit actions, not needed
As suggested by Chrismcmahon, I confirmed that there is no need
to fire the onfocus event. We also remove the convenient functions
around this logic.

Aaron Arcos bd07e7e7a6 Improve e2e tests to check metadata content
The first version of the e2e tests just checked the presence
of some DOM sections. This 2d version actually verifies the
values for most of the components in the viewer.

Aaron Arcos 63021d0b0e Fix e2e tests to support data:URIs
We are using data:URIs to measure performace. This
change broke e2e tests that were trying to match plain urls.
