AppPkg/Applications/Python: Add Python 2.7.2 sources since the release of Python 2.7.3 made them unavailable from the python.org web site.

These files are a subset of the python-2.7.2.tgz distribution from python.org.  Changed files from PyMod-2.7.2 have been copied into the corresponding directories of this tree, replacing the original files in the distribution.
