Addition of changes into the statistics page of the ArchWiki

[PolarianDev]

A lot of people can make lots of small changes and then bump themselves up the statistics of the ArchWiki, and some people who make a few but large changes (such as creating new pages, and spending long periods revising their changes before submitting) will be under-represented.

Also it would be cool to see the number of bytes changed in total (I advice converting it into a more usable figure, keeping it in bytes means people with massive amounts of contributes will have a table column the diameter of the great wall of china, maybe measure it in MB changed? or GB in some cases)
