systemd is checking for xorg now, when trying to apply `localectl
set-x11-keymap`. So we just remove that line (we are not shipping boxes
with X11 either)

We have also updated the date for the local.json example file

travis: get latest packer release with the help of hashicorp api

travis: fix double quotes

travis: no need of echo for export variables

travis: fix typo

travis: fix packer unzip

travis: pull the version via curl just once, and compare fingerprint before importing key

travis: fix gpg command line, since travis run under ubuntu 14.04

We need to re-initialize the pacman keyring for every machine,
otherwise every machine would have the same pacman master key. The same
pacman master key opens the possibility for Mitm-attacks.

The rankmirrors tool is not part of the official arch linux ISO
anymore.. Furthermore I don't think it has so much effect

added travis-ci icon

Make travis validate json

bug fix to PR #21: fixed variable names not committed

As of writing there is no 'latest' (hashicorp/packer/issues/5265)

I'm sorry, I didn't double check what's staged and thus didn't commit fixed
variable names: 'iso_checksum' -> 'iso_checksum_url'

replace iso_checksum with iso_checksum_url

By replacing iso_checksum with iso_checksum_url there is no need to
hardcode hash values into vagrant.json.

Trying to add mirror variable leeds to errors: vars inside variables are not
reusable. See packer issue (#874)[https://github.com/hashicorp/packer/issues/874]

We need a sequence if we want to use the vagrant-cloud post-processor.

Write zeros to disk to improve disk compression

Write zeros to a file on the root partition until the filesystem is
full, then unlink the file. Packer will compress the disk as part of
the build, resulting in smaller final disk image.

I also enabled headless for future headless builds on a buildserver
