This tries to fix a number of related issues:
* the blurred thumbnail was visible for a split-second sometimes
when switching back to an already-loaded image. (Presumably when
JS was sluggish enough to take more than 10 ms to execute.) We
now check whether the promise is pending before showing a placeholder.
(More generally, a lot of unnecessary logic was executed when paging
through already loaded images, like displaying the placeholder, so
this might make the UI a bit more responsive.)
* the blur could get stuck sometimes - I have seen this a few times,
but have never been able to reproduce it, so I'm only guessing, but
maybe the timing was really unfortunate, and we switched back less
than 10 ms before loading finished. We now remove the blur on every
branch, just to be sure.
* adding a progress handler to a promise might not have any immediate
effect, so when switching to an image which was loading, the progress
bar reacted too late. We now store the progress state per thumbnail
so it is always available immediately.
* the progress would animate from 0 to its actual state whenever we
navigated to the image. The change on paging is now instant; the
progress bar only animates when we are looking at it.
* switching quickly back and forthe between a loaded and a loading
image resulted in the loading image becoming unblurred. This seems
fixed now, I'm not sure why. Maybe the "skip on non-pending promise"
logic affects it somehow.
Also removes some unused things / renames some things which were
confusing, and makes an unrelated fix in the image provider, which kept
amassing fail handlers.

Solves the bug, and makes the code slightly cleaner, but it
still does not inspire confidence (e.g. use of viewer flags
by a bunch of callbacks that can run for a background image).
Also, the tests seem underspecified.
I'll follow up with some more refactoring.

* deduplicates URL generating/parsing code
* gets rid of spaces in URLs
* fixes error for file names with / in them (in case they exist;
current MediaWiki seems to disallow such names anyway)

- error caused by select() called during focus event
- HTMLElement not existing in older IEs
- filter rotation for older IEs causing black background bug in IE9
- IE9 lacking progress would have its progress bar never reach 100% and disappear
- Handle e.which value for clicks on IE < 9

Tests which trigger real animations conflict with tests using
Sinon.js fake timers. As a quick fix, disable animations in those
tests.

Bug: 56454

I was going to stage this but better give you the whole enchilada,
it is not that bad, ;-). This is what I am doing:
- Delete things that are not used anymore.
- Componentize image ui element (Canvas).

- the bar now starts at 5% for a visual indication that
something is going on
- the bar animates (fast) to 100%, instead of
disappearing immediately
- the animation logic has been fixed to avoid seeing
the bar go backwards
- added sanity check in all the callbacks to make sure
that we don't apply any changes to an image we are
not looking at anymore (including progress updates)

Everything is under mw.mmv now.
(Also, I cut down on the number of direct global instance references a bit.)
