Adding the uploaded activity photos in the getactivities* methods

[djamelz]

Hello, thank you for the hard work provided on this package. I would like to know if it will be possible to add the (url ?) pictures uploaded by the athlete on activities. It seems that we have hasPhoto field in the getactivities* methods but it always returns false. It 'll be great if the urls could be available directly in the getactivities* response (and not in the getactivitydetails)

Thanks.
