Changed based level example so it can be copied.
Changed based level example so it can be copied.

The base level example doesn't actually work unless enclosed with a "builders" section. All fixed now.

Previous:

    {
      	"type": "googlecompute",
		"account_file": "account.json",
		"project_id": "my project",
		"source_image": "debian-7-wheezy-v20150127",
		"zone": "us-central1-a"
    }

Now:

	{
	  "builders": [
	    {
	      	"type": "googlecompute",
			"account_file": "account.json",
			"project_id": "my project",
			"source_image": "debian-7-wheezy-v20150127",
			"zone": "us-central1-a"
	    }
	  ]
	}
