[packagekit] icons in software update tool

[Jeremy Dawson]

In System ▸ Administration ▸ Update System (in Fedora14), the window 
lists software packages with various icons for each one, in the columns 
headed "Install" and "Status".

Is there an explanation anywhere of what these icons mean ?  If not I 
think it could be valuably added to the gnome-packagekit Manual, and if 
so, a pointer to it could be included in the Update Viewer section of 
the manual

Thanks,

Jeremy Dawson
