The aim for Actions is to be a way to test and build Oolite, its installers, and to be able to distribute it. It should only download what it needs for each stage.
The aim for the all-in-one script is to set up a local development environment that can build Oolite. This script doesn't build the installers, and builds a release version of Oolite. Once set up it is assumed that a developer can modify anything that they want to. It should therefore be sure to always download all submodules.
