Kiwi images, patterns and branding for the MicroOS/Kalpa-based
SteamOS-style variant.

This is the product project, deliberately separate from the package
project. Generic packages live in games:tools and openSUSE:Factory;
only the image, patterns, branding and product defaults live here.

The parent project home:sendz:steamos is intentionally a namespace
only and does not have to exist as its own OBS project.
