We add a README in order to guide newcomers, but add the directory to
.gitignore to prevent packages from being mistakenly added to the repository.

tails-iuk 0.3.7-1 is in the "devel" APT suite.

Tails-IUK 0.3.7-1 includes this patch and was uploaded to our "devel" APT suite.

The version currently in unstable is old and breaks at least YouTube and
Hotmail. This is also closer to what TBB currently ships.

This will bring the 3.x branch that contains many updated rules and also match
what TBB currently ships.

Allow the tails-iuk-get-target-file user to connect to the SOCKSPort dedicated for Tails-specific software.

It already tries to connect there, thanks to
config/chroot_local-patches/tails-iuk_use_dedicated_socksport.patch, but our
newly restrictive firewall breaks it.
