### Promote questions on per-site metas

It's understood that per-site metas don't have their own reputation, and therefore  bounties cannot work as elsewhere. But it's also true that important, difficult issues can get covered by a stream of burnination requests or duplicate support questions. 

I propose that a user with very high reputation should be able to promote one question per month on the meta of their site. The promoted questions would be placed on the featured tab, just as they are on the main site. (They should not automatically go into Community Bulletin, though -- that should be up to voters, as in present.) There would be no reputation spent, and no payouts.
