Remove logging from vspk dependencies
Remove logging from vspk dependencies

Problem:
        having logging listed in requirements.txt makes pip and
        easy_install install an outdated version of the logging package
        from pypi.

Solution:
        remove logging from the list of dependencies. Since it is
        shipped by default with python >= 2.3 this should be
        transparent.
