splitting into aws/vb sections within main Vagrantfile
adding MACHINE_TYPE hash to ease the use of hostnames.
some fixes for small details in the machine resolver portion of the Vagrantfile.
Expanded to include a hash and the mechanism to parse it into a list of machines to build. Placing key, value pairs in the hash will result in one or more machines of a given type being added to the build list. A full build list is present, but commented out for further testing; we don't need to rebuild the entire VPC during testing. Instead of just one machine it now supports and infinite variety.
