Add `files.move_lpt()` function.

And get rid of `minimal_move()`. Hopefully a little closer now...

     This is an experimental function which will hopefully provide a more
     reliable way to send a print job directly to a parallel port (e.g. 'LPT1')
     on Windows systems.  The function body was copied from
     :func:`python:shutil.move()` and "gutted" as much as was practical.
     Note that one difference from ``shutil.move()`` is that in this function,
     the ``dst`` parameter is always assumed to be a directory(-like) path, and
     never a "file" path.  There also is no check for the final destination's
     existence, etc.
     Note that this function's signature differs from ``shutil.move()`` in that
     the ``dst`` parameter is always assumed to be a LPT port, e.g. ``'LPT1'``,
     and never a "file" path.
