StGit: kha/{stable,safe,experimental} updated

The big update since last time is support (in kha/experimental) for hidden patches in the new-infrastructure commands and stack log.

Unless more problems are uncovered, I'll soon move all patches in experimental to safe (which means I'll be recommending that Catalin merge them).
