[python-win32] Single-instance, only when invoked COM localserver

[Michel Claveau]

Hi!

A Python-COM-server contain, essentially, a class. This class can have a 
method  __init__(self, ...)
This methode is called for each "opening" of the COM server.
You can use that for control if your COM-server must, or no, continue.
