Subject: [PATCH] Catch AttributeError as well as KeyError

`ChangeWindowMessageFilterEx` is not always present on Win32 variants. Win32.py already handles this, but catches only `KeyError`. I haven't seen this exception, but I have encountered `AttributeError`, which should be caught as well to avoid a crash.
