Title: Some fixes for the 0.9.8 milestone

* Don't blow up when including an empty state file
* Add ```update_available()``` to the apt ```pkg``` module
* Add a few env vars to the apt ```pkg``` module (idea from [here](https://github.com/puppetlabs/puppet/blob/master/lib/puppet/provider/package/apt.rb#L14))

If I wasn't so bloody tired this evening I'd have gotten more done. C'est la vie!
