graphics/ncview: update to 2.1.7.

2.0: 21 Jan 2010

* ncview now REQUIRES netcdf version 4 with full HDF5 support.  I am not
  going to maintain two code bases, one of which supports netcdf-4 and
  one of which doesn't.  If you need a vesion of ncview that works even
  without a full netcdf v4/HDF-5 install, use ncview version 1.93h.

* If a udunits library is supplied, ncview now requires that it be the
  udunits-2 library.  Support for the udunits-1 library has been dropped.

* Many thanks to Magnus Hagdorn for changes to the package that make it
  more compatible with GNU standards!  All failures in that respect are
  mine; Magnus' contributions were exemplary.

1.93d: 13 June 2008

* Thanks to Seth Olsen for contributing the code to sort the variables
  menus.
