Existing shapefile.py was based on an old version of pyshp.shapefile, but this caused cartopy to use the older version of shapefile, which led to ShapefileExceptions when trying to plot maps.
This bugfix removes the old shapefile.py from the Utilities module and replaces references to that file with the pyshp version.
As pyshp is a dependency of cartopy, it is installed as part of the enviroment.
