Module for running Vagrant without Virtualbox

Vagrant doesn't play nicely without VirtualBox installed. Specifically
calls to `vagrant status` will fail as it tries to run VBoxManage and
`vagrant up` will default to the VirtualBox provider. This commit
mitigates that by:

1. Installing a shim in `/usr/bin/VBoxManage` which responds to --version
   with a genuine VirtualBox version and for all other commands justs
   exits with success.
2. Changes `/usr/bin/vagrant` from a symlink to the real application to
   a similar shim which detects if the first argument is `up` in which
   case it forces `--provider=vmware_fusion` onto the list of args.

Hacky, but it works...
