Update to 0.005
    
    - New upstream release 0.005
      - Introduce rcopy(), a stripped-down replacement for
        File::Copy::Recursive::rcopy()
      - Implement copying of symlinks within all three public functions; at this
        point we should be able to make substitutions for File::Copy::Recursive's
        fcopy(), dircopy() and rcopy() functions in a large proportion of toolchain
        libraries, particularly in test suites
