There used to be a CSS trick with the order we added things to the
page and removed them from it, but it doesn't seem possible anymore
with the new order of execution, with the overlay appearing
immediately and being taken care of inside bootstrap.
The main cause of the bug, however, was the hash reset happening
after the interface was closed.
Doing the scroll restore with jQuery.scrollTo is more future-proof
and testable in QUnit.
Additions were also made to the cucumber E2E test because QUnit
alone wouldn't have caught the hash issue.
This also cleans up custom events a little and reintroduces
pushState on browsers that support the history API.

I went for this option because it was the fastest to implement.
I think we should wait until we make the change to core to expose
image dimensions before we consider switching to another strategy.

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