Sequential Upload and Proper Sharing Status Count

Current upload system i believe it tries to upload using bulk, for example trying to 10 photos at the same. However, for event where internet connection is bad/slow, this system is not good because once there is enough backlog, the chance for failure increased, it keeps getting worse.

My suggestion is to add option to upload sequentially. FIFO.

Another issue is the Upload Sent Count, i think it’s calculating total sent (including failures). It should be counting total session or files not including failures.

Tested on v8.2.0
