update to work against 2.1.0.  note hardcoded 2.1.0 dependencies in places, and some inefficiences (does not cache the postgres jar for instance).  but working.  and much faster.
several tweaks for multi-node remote deployments:
* ensure it is java7
* do tar xvf or tar xvfz
* create more directories as races mean some aren't created in time
* use a flag to ensure only one initial node runs as there have been races populating the DB
