QPID-4952: Renamed the Swig Python binding module to qpid_messaging
QPID-4924: Moved existing Python examples to the bindings example directory.

They now sit alongside the Perl examples.
QPID-4924: Fixed the Python examples to use the new Python module

Now the imports will first attempt to bring in qpid_messaging, the Swig
generated Python. If that fails it will then fall back to trying to
import qpid.messaging, the pure Python binding.
QPID-4924: Created the console Python example app.

It allows the user to send messages tot he server example app and get
messages back.
QPID-4924: Fixed out the server Python example shows values

When the values weren't being treated as strings then they would raise
exceptions.
