Fix typo in the deployment file
Change the way that the cluster starts up.

Distribute the deployment and schema files to all hosts, then start
volt on the first host, then use create - not add - on the other
hosts.
Combine master and slave functionality into default recipe.

After looking over the voltdb docs again, I found a simpler way
of starting up a cluster.  Use the 'add' command to join an existing
cluster, and the 'create' command - on each initial host - to start
the initial cluster.
