[jimtabor] 35022: - Implemented NotifyWinEvent, SetWinEventHook and UnhookWinEvent. - I only enables test_winevents(), test_set_hook() and all related with wine Msg tests. The test takes a while to run due to the IsWinEventHookInstalled check. I optimized our mask set to take this into account. The results are, the test is slow and our code is fast. - We pass all Event and Local Hook tests. Will research the problem with global hooks and finish it up.

Log:
- Implemented NotifyWinEvent, SetWinEventHook and UnhookWinEvent.
- I only enables test_winevents(), test_set_hook() and all related with wine Msg tests.
The test takes a while to run due to the IsWinEventHookInstalled check. I optimized our
mask set to take this into account. The results are, the test is slow and our code is
fast.
- We pass all Event and Local Hook tests. Will research the problem with global hooks and
finish it up.
