Project lifespan

[StrykeSlammerII]

The redaction feature is essentially a "medium-delete" per UF #819. That issue has been open ~5 years, and put in "long-range planning" a few years ago. This sprinkle is my effort to provide an alternate starting point in the meantime. Redaction here will likely be deprecated whenever that issue is closed, depending on how exactly it's handled.

The "self-termination" button may have a different lifespan. Whether a single button is useful as a separate sprinkle may be up for debate.

UF5 doesn't have a self-delete button yet, and I think it would still be useful for others.
"Medium-delete" may be on UF's 5.1 milestone, but until it's actually live-and-working I will keep redaction here.
