rpm-ostree: Display all available deployments, display changed packages, fix author & origin
rpm-ostree: Display all available deployments
List all deployments in the interface so that users can see the effects of updates. This will be usefull later once we add support for rollback.
rpm-ostree: Display added or removed packages
List installed, locally installed, removed and replaced packages for each deployment.
rpm-ostree: Prettify origin name from ostree remote
OStree remote names are usually lowercase, so make them pretty by upper casing the first letter for now.
rpm-ostree: Add (harcoded) author
Harcoded value for now. We will figure out where to get that info once we have multiple users of this backend.
