Updated python3 module pytz for use with this project.  The newer version supports python3, so I don't need to include my custom-modified version which I made to support python3.  Updated relevant documentation also.   Added more documentation for pyswisseph build failing on Python 3.4.
Updated the GeoNames class to handle the updated RESTful webservice API which now requires a username specified.  Added logging output to print out 'Exiting' upon exiting of the main application window.
