Log Message:
Update to 1.4.5. From Changelog:

- Can now deserialize more AMQP types.

    Now handles types ``short string``, ``short short int``,
    ``short short unsigned int``, ``short int``,  ``short unsigned int``,
    ``long unsigned int``,  ``long long int``, ``long long unsigned int``
    and ``float`` which for some reason was missing, even in the original
    amqplib module.

- SSL: Workaround for Python SSL bug.

    A bug in the python socket library causes ``ssl.read/write()``
    on a closed socket to raise :exc:`AttributeError` instead of
    :exc:`IOError`.

    Fix contributed by Craig Jellick.

- ``Transport.__del_`` now handles errors occurring at late interpreter
  shutdown (Issue #36).
