 Version 1.10.0 of python module dnspython got released.

 The attached patch updates the port to the latest version and adds support
 to python 3.0 and newer.

 Because the distills for dnspython and dnspython3 differ only in some
 details both are handled by this single port file depending on the desired
 python version.
 Less confusion to the user (py27-pymysql and py32-pymysql produce the
 desired module) and easier to handle as a dependency in other ports IMHO.
