BuddyCamp.org DNS and nginx aliases, wildcard certificate

@camikaos and I would like to start creating sites for BuddyCamps on the WordCamp.org multisite installation, but using the buddycamp.org domain. The domain is already in MarkMonitor and Matt gave the ok to use it.

Could someone from systems/@nacin please setup aliases in DNS and nginx?

We’ll also need a wildcard cert for buddycamp.org, since we’re ready to FORCE_SSL_ADMIN across all WordCamp.org sites.
