Asynchronous photo uploads

[jmathai]

This maybe addressed by UIProgressView in #33 but the user should be able to start a photo upload and continue using the app. Perhaps they will take another photo and upload that one too both in parallel.

ok. So we should not have a progress bar, but a notification when the user has his photo uploaded. I will check what we can do for this issue. I will label it to Release 1.2

It would be nice to show the progress of each photo. I remember seeing this with vimeo's iphone app. But we can do it in phases -- not all at once.

I will check vimeo's upload.
But #33 has priority, then we do this one in two steps: first multiple uploads (btw, it is in a thread today, so we just have to call multiples times) and after progress bar for each photo.

I think this will be dependant on #52. We probably don't want to simultaneously load several photos into memory at the same time. Moved #52 to 1.3.1.
