Customizable Automated Post Deletion threshold

[revi]

Pitch

For now I can only select pre-chosen timeframes for age threshold. It'd be better if I can choose my own timeframe. (If desirable for performance reason you might enforce "minimum threshold" (for example "I can only delete toots after 1 week"[because 1 week is the current minimum] I think))

Motivation

I might want to delete toots after 3 weeks, 3 years, {n>2} years, 4 months, 9 months, but it is not possible.
