    use archiver for tar. use streams for gzip.

    this removes the need to manually copy files to a new dir and to use a
    special fstream. tar file sizes changed a bit since archiver uses the
    standard 512 bytes per block vs 256 bytes that node-tar was using. this
    may become configureable through archiver in the future.
