    Refactor the image download and checksum computation bits

    Prior to this patch downloading and computing the checksum of the image
    were done in different stages, after the download the file would need
    to be re-read and the checksum was computed. This patch is changing it
    by creating a ImageDownload class which computes the checksum at the same
    time the image is being downloaded, this saves time and also make the
    code more portable.
