Bring the wiki up to 0.2.0: events, webhooks, projects, proxy export, groups
Bring the wiki up to the current warden Installing by name works now, so the pages say so instead of explaining why it does not. Adds what the fleet gained since they were written: pool and listeners across every node, a name two machines both hold, --node forwarding on register, release and heartbeat, the dashboard's fleet mode, and the new heartbeat command. Records that forwarding takes a person's token rather than the cluster one, and why. Also that the dashboard shows this machine's ports with no warden running at all, which was the last place the two ways of asking the same question still disagreed.
Write the wiki Nine pages: what warden is, how to install it, running it on one machine, seeing and freeing ports without a server, running a cluster, and three reference pages. Plus a troubleshooting page built around the messages warden actually prints, so a reader can search for what they saw.
