Major packaging change to work around parallel calls - stopped zipping targets from having direct dependency on 'sf-preprocess-package-config', and instead have 'sf-zip-content' call 'sf-preprocess-package-config' if needed. Changed 'sf-prep' to call a target that wipes out the 'generated' directory. It's not perfect but it gets us going again.
