Uploads

Hi! I love your work so far. I've added a rather naive file upload implementation and updated the web application to demonstrate it. I didn't have much time to figure out the correct way to correctly submit the file upload along with all the other optional arguments, so instead I simply set those things after the file upload's completed. 

I've also added a Spring Batch-based file downloader which can be used to download all of ones photos in bulk. 

The pieces are rough, but I hope you'll consider integrating some of them. Thanks!
