This patch does intentionally not touch any file name. Some of the
file names are a little weird now, e.g. \Cite\Cite. These can more
easily be renamed in later patches.
I used https://codesearch.wmflabs.org/search/?q=new%20Cite%5C( and it
looks like this code is not used anywhere else.

Note this codebase appears to be dual-licensed. Some files mention MIT,
but extension.json and some other files mention GPL.
Since WMDE typically uses GPL, I will continue to mark the files we
created as such.
