ux(developer): a view of issues that have been lost in the tracker

[gforsyth]

We drop the ball sometimes because open-source can be hard. We are good at triaging, but we want to be better at making sure issues don't fall through the cracks (some reporters are good at keeping us honest, others might be worried about "bothering" us).

We want views of:

• open issues that haven't had a comment in $TIME_PERIOD where the last-commenter isn't a member of the project
  • we can use this to filter for things that we've missed (this could even add a label to those issues and we can create a specific view of those issues)
• open issues that haven't had a comment in $TIME_PERIOD where the last-commenter is a member of the project
  • we can use this for determining if we need to bug a user to provide more context, or to check on if we should close something out as abandoned.
