stubs for global option getter/setters
Policy Object Ready added to kadmin module. tp_alloc and tp_free should be working as expected.
Python 3.x compatible + Minor compare change

pykadmin.h now sets up the environment to support python 3 compilation.
Both Python 2.6 and Python 3.3 have been tested and build without
issue. Both versions pass all unit tests.

Compare TL data now will recurse upon the tl_data_next member for a
deep compare (rather than the top data only)

Unit tests have been modified for python 3 support (strings are encoded
and decoded when sent to subprocess) . input is used instead of
raw_input for the initial confirm.
