Point checkin. Rough cut at href merge op (don't use it yet though).

Also included abort() method on progress object.

 What's left:
   o put incremental update in looping thread(s) to let system bootstrap from nothing
   o deal with store/webapp going away
   o deal with virt server down
   o Switch to using virtualized snapshot instead of HEAD in staging
   o testing... and lots of it
