Tie custom channels into channel-contents.tt.

We should now get an overview and help text on how to add a particular channel and also a bit of information about the builds that are required for a channel to get upgraded.

Right now we only select the latest successful build in the latest successful evaluation, so if someone wants to have more information about which channel has failed, (s)he still has to look at the "Channels" tab of the jobset.

We can make this more fancy at some later point if this is really needed, because right now we're only interested in the latest build, because it's the only thing necessary to deliver the channel contents.
