Make FSMLoggerAdapter compatible with Python 2.6
Make FSMLoggerAdapter compatible with Python 2.6

Python 2.6 does not use new style classes in the logging
subsystem, but the super call requires the parent to be
a new style class.

This patch updates the code to use the old way of calling
parent's constructor.
