Merge ~cjwatson/launchpad:charmrecipebuild-traversal into launchpad:master

[Colin Watson]

Add +charmrecipebuild stepthrough navigation on BuilderSet

This is useful when repairing the build farm after outages, or otherwise needing to look up a charm recipe build by its ID alone. It goes with similar stepthroughs for other build types.

Compare the very similar https://code.launchpad.net/~cjwatson/launchpad/+git/launchpad/+merge/417863.

[Jürgen Gmach (jugmac00)]

Can you think of a place where to document this?
