Recent live-build asks tasksel to install the "standard" task, which pulls a
bunch of new, unwanted packages that were not shipped in previous Tails
versions.

Let's deinstall those packages.

Refresh and apply our Tails-specific useless controls removal patch.

Thanks to Marco A. Calamari for the suggestion.

I sadly haven't the skills needed to do the same for Arabic => not touching it
since I fear making things worse.

This is actually developer documentation. Our developer documentation tends to
move quickly, and the rest of it is not translatable.

The source package build-deps are needed to build the tails*.deb binary package
that itself, once installed, will eventually provide every tool needed to build
Tails images.

E.g. the current Ubuntu LTS (Lucid)'s Seahorse does not support this :/

E.g. Ubuntu has Seahorse installed by default, but not the needed Nautilus plugin.

This reverts commit 0244e86d.
This reverts commit 30c1d3c3.
This reverts commit 157f8103.

The primary mirror (archive.torproject.org) now provides HTTPS and does not work
anymore as part of the round-robin pool.
Let's make the others a secondary mirrors pool then.

Intentionally empty to override the one in the server's underlay: this
page is an orphan one, not really useful for Tails purposes, and is
quite long/costly to build and update.

Every wiki file attachment lands onto the generated ISO images, which can become
quite costly over the time:

  - remove old Vidalia packaging files
  - convert big PNG screenshots to JPG.

It is far less buggy. It adds 2MB to the final ISO size, which I earned (ah ah)
by fixing the initramfs LZMA compression that saves much more.
