*: web, web_unsplash
Without this commit, the user had no hint to know something was actually
being performed.
It would be worst when uploading multiple image at once, eg in image
wall, as it could take some times for the images to be processed and
uploaded.
The user now has a visual hint about the upload progress through a
toaster and some progress bars.
For unsplash, note that as the actual image download is performed S2S,
the progress bar will automatically jump to 100%, then will wait for the
RPC success once the server is done to show a success progress bar.
