[python-win32] COM server support on Vista

[Michel Claveau]

Hi!

Because Protected mode need to activate UAC, I prefer to test (to try) on a 
virtual-PC. I have done a Vista-premium with UAC on, Security center on, 
Protected mode on.

In the passing, I benefitted from it to test my procedures of installation 
for Vista.

Results :
    iebutton: install OK ; run OK (a "bit" slow)
    ietoolbar: install OK ; run OK.
