[Python.NET] Fixes for interface inheritance and abstract

Problem 1 can also be seen on ADODB.Connection. It is not specific to COM,
Interface ICollection inherits from IEnumerable. In C#, if I declare a
variable as ICollection, I'll see GetEnumerator. In Python, if I cast to
ICollection, I do not see GetEnumerator. I think this is because interface
inheritence is a different animal than class inheritance. It seems to be more
contractual than structural.
I sent a workaround to Brian. The fix is probably not the best way of doing
it, and is probably not complete, but it does seem to help.
I noticed as well that properties on interfaces don't work, e.g. I have to call
get_Count() rather than just accessing the Count property.
from CLR.System.Collections import Hashtable, ICollection
ht = Hashtable()
c = ICollection(ht)
print c.Count #fails
A fix for this is also sent to Brian.
