Removed the git@github.com lines as it blocked cloning as an anonymous client. and updated to 1.4.3

Removed the git@github.com lines as it blocked cloning as an anonymous client. This resulted in RSA keys not available errors. 
Also it looks like that Vagrant 1.4.3+  mounts on /tmp/vagrant-puppet-1/ and not /tmp/vagrant-puppet/  added an additional folder_sync line to create expected behaviour. All runs now except the missing file /etc/puppet/hiera.yaml which seems to be missing on the box and throws a warning but does not stops the provisioning.
