[IronPython] Interaction with other CLR code

[Curt Hagenlocher]

Some more thoughts on this topic.

Unresolved:
1. How to handle properties?  If we were to map properties in a
CLR interface onto Python properties, we wouldn't be able to
handle indexed properties.  Indexed properties could be handled
through get_PROPERTYNAME and set_PROPERTYNAME functions on the
Python objects.  Then, do you use a Python property to implement
a nonindexed CLR proprty and a Python function to implement
an indexed CLR property, or is this too inconsistent?

2. What should be done with out parameters?

Actually, you might even be able to do better than that and
store these assemblies on disk in a well-defined place, meaning
that on subsequent runs you could skip the codegen phase.

I've got this code working now and will post it after some minor
cleanup.
