Initial vCloud support

Modified script and template for vCloud support
Set up DNS in minimal script

The vCloud boxes we have don't have DNS configured properly, so this sets up
DNS using Google's servers.
Change README to reflect use of Vagrant 1.4.3
Remove DNS settings in setup scripts

This has been fixed on vCloud, and was also a bad idea as it would break support for other platforms.
