fixed #14 and #15

login response is now

    {
      "result": {
      "user": {
      "email": "stdavis@utah.gov",
      "name": "Scott",
      "agency": "AGRC"
    },
    "token": {
      "token":
        "zPPCZRHedo8",
        "expires": 1381249580000
      }
    },
    "status": 200
    }

The date can be used in js like `var x = new Date(1381249580000)`

Also made all json properties lowercase by default and removed tedious PropertyName attributes.
