Title: Added apt-cacher-ng with feedback from jacknagel

Jack also asked what the use case was for this software.

My primary use case is installation and updating of virtual machines, and I use apt-cacher-ng to keep downloads to a minimum.

The blurb from the homepage reads: A caching proxy. Specialized for package files from Linux distributors, primarily for Debian (and Debian based) distributions but not limited to those.
