Enable VMware Fusion without manual workarounds, stop copying config to submodules, allow access from the host

1. Added some chef recipes to remove most of the manual tasks necessary when using the VMware providers.
2. Changed the launch scripts to point to the custom config files rather than copying them into the submodules.  (I got tired of seeing dirty submodules when I didn't change anything.)
3. Made some config changes to enable access to Cloud Foundry from the host via the vcap.me domain
    * Forwarded ports 80, 8080, and 8181 from the host to the guest.  (Port 80 may be an issue for some.)
    * Made the cloud controller listen on the primary network interface instead of localhost
    * Added an iptables rule to DNAT localhost:8181 to the primary network interface so the cloud controller still works locally.
