    Make sure videos disguised as MP4 aren't unhandled
    
    *.mp4 files were ignored if they were actually detected
    as any other type. This was the case for 3gpp files, but
    it would happen for *all* files types that weren't listed.
    
    And we can't list every file type as possibly being a quicktime file.
    
    So we ignore files that are text/plain, or a sub-class of it.
    
    This makes FLV hiding as an MP4, or 3GPP hiding as an MP4 work
    correctly.
