IPTraffic 0.8.2 - v2

IPTraffic 0.8.2 - v2

This is actually just a different way to publish the already published
'IPTraffic'-addon.

The code is identical, I just deleted a few trailing spaces
and some unnecessary tabs.

For discussion and reasons see:
=> https://lists.ipfire.org/pipermail/development/2021-January/009153.html ff.

I now rewrote the build process so I could drop the former used tarball.

The code is now more transparent - I'm hoping that "someone" is willing/able
to start reworking or integrate it as an addon or as part of the core system.
