Git commit 8212cc76c0d51dfbac96a7c6ba4196d3f7f60ae3 by Jonathan Thomas.
Pushed by jmthomas into branch 'master'.

Add Backend::addArchiveToCache(), whichs adds .deb files for the candidate versions \
of existing packages to the apt .deb cache. This function can be used to add .debs \
from e.g. a USB stick so that computers without internet connections can update \
packages.
