Campsite + Discourse Integration

Keep Campsite and Discourse aligned: when communication events happen in one, update the other automatically.

Example: when Discourse's "Watch Events" fires, WEXTL can "Create a DM Message" in Campsite. Campsite has 12 actions (including Create a DM Message, Create a Message, and Create a Post); Discourse has 94 actions (including Abort Multipart Upload, Activate User, and Add Group Members).
