Adding pagetraffic information

[prototyperspective]

This isn't nearly as important as many of the other issues here but maybe it's easier to add than it seems.

Wikipedia uses https://github.com/MusikAnimal/pageviews and the most recent page traffic can be viewed by going to "Page information"->"Page views in the past 30 days".

See the links in the readme of that repo...maybe there already is info on how to add this other MediaWikis. If not somebody or I could ask about it.

Having this information could be very useful because you can get a sense whether putting in a lot of effort into improving an article is worth the effort and because it may be a motivation.
