Vagrant 1.2.x configuration with Vmware Fusion support

So I've been using that for a few days now and believe this is the way to go.

- it updates the vagrant config to the new configuration format, introduced in Vagrant 1.1

- it adds an additional vmware fusion configuration and I uploaded a ready image to my people.m.o space

downside:

if I understand https://github.com/mitchellh/vagrant/issues/1475 correctly everyone using vagrant would have to upgrade to at least 1.1 (1.2.7 is currently the recent version)
