[darwinbuild] xar subdoc usage

[Rob Braun]

I've made a first pass at trying to include some of the darwinbuild
related metadata in the xar archives created by packageRoots.
Basically, I've added a darwinxref module that just takes the 
project information that is in the plist from the database and 
exports it in either plist or xml style like exportIndex does.  
Then packageRoots calls this, exports the information in xml format,
and has xar add it as a subdoc in the archive named 'darwinbuild'.
