Updated mediawiki/skins
Project: mediawiki/skins/BlueSky  a7a098268bbc482bf4c8915169223ff675fea25d

Removed code related to wikiHow's BounceTimeLogger extension.

A better way to achieve the same functionality in a self-contained,
skin-agnostic way would be to hook into SkinAfterBottomScripts hook in
BounceTimeLogger's setup file.
