This creates lists that can be included in to each other. This is done by hack that original script calling one of these lists passes base URI to access sources and that is later reused. This is how relative URI should work in future but it is not completed now so we can overcome it this way and have almost same support. This also means that we no longer have to specify target branch for lists because it no longer matters. Fallback branch is for now dropped because we are not doing small build at the moment. We should in future return to them but they will be implemented differently then fallback branch is. This also does some base list cleanup.
