    squash! Bug 19273: Avoid JavaScript patching of the external app helper dialog.
    
    When handling an external URI or downloading a file, invoke Torbutton's
    external app blocker component (which will present a download warning
    dialog unless the user has checked the "Automatically download files
    from now on" box).
    
    For e10s compatibility, avoid using a modal dialog and instead use
    a callback interface (nsIHelperAppWarningLauncher) to allow Torbutton
    to indicate the user's desire to cancel or continue each request.
    
    Other bugs fixed:
     Bug 21766: Crash with e10s enabled while trying to download a file
     Bug 21886: Download is stalled in non-e10s mode
     Bug 22471: Downloading files via the PDF viewer download button is broken
     Bug 22472: Fix FTP downloads when external helper app dialog is shown
     Bug 22610: Avoid crashes when canceling external helper app downloads
     Bug 22618: Downloading pdf file via file:/// is stalling
