Offline2

I wanted to get the massive changes for offline into master this week, so Tim can start the restructuring he is thinking about.  This offline effort is not complete. I have not included, or started tracking, of xs-config, and xs-setup, which will be part of the offline install process (eventually replacing ./runansible).

But I have verified on a x86_64 VM that the standard "./runansible" runs to completion successfully, on a non-gateway install.
