Everything is under mw.mmv now.

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.

fileUsage tests were applying styles to the fixture element, which
apparently does not get cleaned between tests. This was because
fileUsage.$container had different semantics from element.$container
(widget's own container div vs. parent container div). FileUsage
now inherits from Element to make sure behavior is consistent.

* more robust method of obtaining URL
* decouple performance logging from providers (mostly)
* ignore fake XHR object which jQuery returns for JSONP requests
* guard for CORS requests - apparently Chrome refuses to return
certain information even with an Allow-Origin: * response header.
* Resource Timing is limited to 150 results, which causes fake
misses in debug mode. There is an API to increase the limit
but it is not implemented in Chrome. I am calling it nevertheless,
maybe IE understands it (it is present in the MSDN docs at least).
This seems to work for AJAX, CORS, JSONP, image AJAX; CORS requests
return 0 for a lot of values, per spec a Timing-Allow-Origin: *
header might help that.

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.

* userinfo api requests are cached now
* we use jsonp only if we have to (makes gender api calls measurable on WMF wikis)
* all API calls use providers now, provider.Api constructor can be used to
wrap mw.Api with metrics
Does not return a proper model, and gender API calls are not preloaded together
with the rest of the calls. Maybe next time.

The code was incorrectly adding the link to the first section
no matter what. This wasn't caught by the existing assertions,
so these are being improved as well.

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.

The code to load and set the image was semi-duplicated and
scattered in various places. This was the source of defects
as this code is called asynchronously and was hard to debug.
This change attemps ot consolidate all the image load logic
in one place. It also adds sorely needed unit tests.
