So this looks OK, but I can't tell if it ensures you get the difference between 
successful builds rather than the difference to the last build - we need to 
ensure that a failed build of a recipe in between isn't considered as part of 
the comparison. In practice I guess this would mean storing the buildhistory 
revision of the last successful build for each recipe.

Cheers,
Paul
