[IronPython] Pickle-Serialization integration

[J. Merrill]

You could implement ISerializable on Python objects by pickling the object (using the regular Python pickle mechanism) and using the resulting string as the serialized value (perhaps with some kind of sanity-test header and/or trailer).  Unserializing would then require unpickling the serialized string.
