Summary: Allow multiple type libraries

Initial Comment:
As explained in my post to the python-win32 mailing list ("How to write a COM Server implementing interfaces from type lib?"), I have patched the policy.py to support multiple type libraries.

This should work in parralel to the exisisting one-type-lib feature. Using the changed version, a new attribute can be used in the COM implementation class called "_typelib_interfaces_". This attributes is expected to be a list tuplse of the library CLSID string, the major and minor version, the LCID and a list of Interface strings. 

Here is an example I used in my server:

class OPCServer():

	(...some other attributes...)

	_typelib_interfaces_ = [ 
		("{3B540B51-0378-4551-ADCC-EA9B104302BF}", 3, 0, 0,
			[
			'IOPCServer',
			'IOPCItemProperties',
			]
		),
		("{B28EEDB1-AC6F-11D1-84D5-00608CB8A7E9}", 1, 0, 0,
			[
			'IOPCCommon',
			'IConnectionPointContainer'
			]
		)
	]

Actually, the patch includes some comment that say "PATCH START".
