Log:
- Add support for shell window hooks in win32k, based on trunk's code. It's not
beautiful however it's well isolated and easy for future merges.
- The proper code for keeping a list of registered windows for shell hook notifications in
desktop structure is commented out for debugging purposes, and the list is global atm.
- Thanks to Maarten Kroese, this work is partially based on his patch.
