"Backups" feature

[bryanjclark]

Often, when I've dialed in an animation, I want to be able to create a "backup" so I can go experiment more, knowing that I have a save point if I want to go back.

It'd be neat if we had the ability to create/update/read Backups. I would like that they use the same visual format as the email template we use when sharing a set of tweaks.

One interesting bit that'll arise from this: what happens if the underlying TweakLibraryType changes? Do we need some kind of randomly-generated-from-a-deterministically-derived-seed thing (where TweakStore creates a "version name" to ensure that a Backup can only be restored if the underlying version name is the same?)

Well, more than two years in and we haven’t needed this badly-enough to build it. Let’s close this issue.
