    actions-popover: Add "Send file" option
    
    The problem is that with the current file transferring
    DnD mechanism, users may not be aware of the fact that they
    are able to send files to guests which have this ability.
    
    Using this option, in following patches users will also be
    able to transfer files to a SPICE guest using a more intuitive
    click of a button.
