Bug in Update list item example

[wilsoncpw]

There's a bug in the 'Update List Item' example.

The line:
Content-Type: "application/json"
should be:
Content-Type: "application/json;odata=verbose"

Otherwise the __metadata in the request body doesn't get sent correctly, and the API returns a '400' error response.
