Ensure package installation is non-interactive

[Alexandros Frantzis]

Installation of package dependencies is currenty performed using "sudo apt-get install -y --force-yes". However, this is not enough to ensure unattended package installation, as some packages contain custom debconf configuration which blocks the process (e.g. gdm). We need to define the env. variable "DEBIAN_FRONTEND=noninteractive" to make the installation really non-interactive.

Here is a patch for this:

I love debconf!
