    downloader: Report progress of already running downloads
    
    This is actually more like reporting progress of duplicate downloads.
    Duplicate downloads can currently happen for two reasons:
    
    1. We automatically download logo and drivers for known ISOs and
       devices as part of wizard's menu population. Now if user launches
       Boxes with path to one of these ISOs/devices as argument, we'll have
       two downloads launched for logo and driver files. Since automatic
       download will be launched first, user will see no progress of
       download reported at 'preparation' step of wizard (just a stuck
       progress bar).
    2. Multiple different OSs sharing logo and/or driver files and user
       having ISOs for at least two of them. This is currently not a problem
       since we don't allow multiple instances of wizard (or Boxes itself)
       running at the same time and progress of automatic downloads isn't
       reported to user. However, either of these could change in future.
