* Add a new module ext.cite.style to load the new CSS.
* Add a ResourceLoaderFileModule that adds the correct CSS file
depending on the content language, so that the visual style of
citations can be changed per-language.
The main ext.cite.style.css file renders similarly to MediaWiki's
default Cite style. Also, an example CSS for Farsi numbering is
included.
