update for VMWare Fusion provider to recognize Fusion 6.x

update for VMWare Fusion provider to recognize Fusion 6.x and Hardware Version 10

Without this patch, creating a vm with VMWare Fusion 6 requires that users manually give input to a prompt that asks about upgrading the VM.  Screen shot attached.  This patch resolves that issue in the same way that the issue was handled for VMWare Fusion 5.
