Z-Image Split-Sigma Workflow: ZiB to ZiT

<p>Z-Image 5.0 EmberFrame is the current recommended version of the standard split-sigma ZiB to ZiT workflow. This is a small usability and cleanup release rather than a dramatic rebuild: the EmberFrame helper nodes now live on GitHub, the public version names now match my local files and GitHub repo, and this version is the baseline I plan to build on going forward. Older 4.0 and 4.6 downloads remain available for reference, but new users should start here.</p>
