Subject: [PATCH] Support custom Ice::Dispatchers in Python (sort of).

This is a very thin shim to expose the InitializationData::dispatcher
member, but not a way to implement an Ice::Dispatcher in Python.

Extend the wrapped Ice.InitializationData to check for a 'dispatcher'
attribute. In Python, the user is to pass in a PyCObject-wrapped
Ice::Dispatcher*.

The custom Ice::Dispatcher must still be implemented in C++, and also
exposed to Python in some way.
