I want to add env variables to new instances

I want all my deployments to have access to postgres, thus I'm creating a plugin which sets up a new user with access to a new database (on a postgres server in a different container).

Fix bootstrap on clean install

On a clean Ubuntu 13.04 install, the bootstrap script fails with:
make: apt-add-repository: Command not found
make: *** [docker] Error 127

This happens because 'software-properties-common' needs to be installed.
