File download issues

[cjh1]

There are a couple of problems with the file download functionality. The first is that the download url being used is pointing at the item, rather than the file.

http://localhost:9999/api/v1/item/570baab10640fd7385687099/download

this should be:

http://localhost:9999/api/v1/file//download

The second is the Girder-Token needs to be send with the download request or the server will not be able to determine the user and thus whether they are authorized.

@TristanWright Let me do a little more investigation on my end, it seems that the download work intermittently! Not sure how or why.
