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.

+"""Convert "arbitrary" sound files to AIFF (Apple and SGI's audio format).
+
+Input may be compressed.
+Uncompressed file type may be AIFF, WAV, VOC, 8SVX, NeXT/Sun, and others.
+An exception is raised if the file is not of a recognized type.
+Returned filename is either the input filename or a temporary filename;
+in the latter case the caller must ensure that it is removed.
+Other temporary files used are removed by the function.
