Location changed:

Release 1.1.1

CHANGELOG & Modulefile updated.

Signed-off-by: Ken Barber <ken@bob.sh>
Add optional architecture qualifier to apt-sources
Install required_packages before 'apt-get update'

This is necessary when required_packages contains GPG keys that are used for
authenticating other packages. Tested with package ubuntu-cloud-keyring which
is included in Ubuntu main and used by the Ubuntu Cloud Archive.

I think the same problem applies to other *-keyring packages as well.
Add geppetto project definition
Update .gitignore
apt::pin: handling all apt preferences properties

The two forms of APT preferences records (general & specific) can now be
completely and not partially defined. All distribution properties can be passed
as resource parameters. This change is totally backward-compatible.
