Feature request: allow subreddit comments page filtering by account age

[ghost]

For instance

1. browse to subreddit comments page at /r/subredditname/comments
2. be able to filter by account age (e.g. only show comments from accounts newer than x days/months)

This would help us see who is creating alternate/sockpuppet accounts after being banned.

That would be extremely heavy on the API rate limit, which makes it not really usable as you will have to wait a long time between each time using it for the rate limit to reset.

@creesch can toolbox cache account ages locally or on a wiki page (or does that violate TOS)? It would be heavy on the API rate limit the first go-around, but minimally after that.
