Method to prune/leave feedback in Kvetch

[ninjaWR]

I just saw two items about how it would be nice if upgrades were easier and if there was an automatic upgrader, and it got me thinking that there's no way to leave feedback or flag it if you're logged in.

It would be nice if there was some way to either leave feedback for when a Kvetch is no longer "valid" (for lack of a better term) because something has been implemented to address it, or to flag it for someone else to look at it and decide that it should be removed.

This could also be useful if a spam item was displayed, or if an offensive message was left.
