Feature/separate db ws servers

This branch allows for separate servers to be designated to be a dedicated database server or a web server.
This includes sample configs for dedicated servers and a single server which has been tested with the 1.0.10 release.  

NOTE!: Since certain components (postgres and tomcat) have been split out from the master scripts, the remaining parts of the master script will not be compatible with JSON configs before this. I'm not sure if this the best approach or to allow duplication (and effectively let our scripts fork).
