Sunset issues that have been open for more that 2 years

[wdduncan]

In order to clean up the RO issue tracker, how about we sunset/close issues that have been open more than 2 years? If the submitter is still passionate about the issue, it can easily be reopened. Also, perhaps some of these issues are best moved to the Discussions tracker. Although, I'm not real sure what counts as an issue and what counts as a discussion in RO.
