Add middleclick-autoscroll

Middle-click autoscroll for every Chromium-based application on the system -
Electron and CEF applications, Chromium-based browsers, Flatpaks, Spotify and
Steam - plus anything installed later. Built from source out of the upstream
release tarball, like cachy-auto-update.
