Andrew Eikum c1c3198aa4 user32: Don't always insert menu items during WM_MDISETMENU. 
MSDN says WM_MDISETMENU shouldn't change the frame menu if it is given
as NULL. Tests bear that out. Some other tests are included to show we
haven't broken behavior on e.g. initially maximized MDI child windows.

*
* Notes: Fairly complete implementation.
* Also, Excel and WinWord do _not_ use MDI so if you're trying
* to fix them look elsewhere.
*
* Notes on how the "More Windows..." is implemented:
*
* When we have more than 9 opened windows, a "More Windows..."
* option appears in the "Windows" menu. Each child window has
* a WND* associated with it, accessible via the children list of
* the parent window. This WND* has a wIDmenu member, which reflects
* the position of the child in the window list. For example, with
* 9 child windows, we could have the following pattern:
*
*
*
* Name of the child window pWndChild->wIDmenu
* Doc1 5000
* Doc2 5001
* Doc3 5002
* Doc4 5003
* Doc5 5004
* Doc6 5005
* Doc7 5006
* Doc8 5007
* Doc9 5008
*
*
* The "Windows" menu, as the "More windows..." dialog, are constructed
* in this order. If we add a child, we would have the following list:
*
*
* Name of the child window pWndChild->wIDmenu
* Doc1 5000
* Doc2 5001
* Doc3 5002
* Doc4 5003
* Doc5 5004
* Doc6 5005
* Doc7 5006
* Doc8 5007
* Doc9 5008
* Doc10 5009
*
* But only 5000 to 5008 would be displayed in the "Windows" menu. We want
* the last created child to be in the menu, so we swap the last child with
* the 9th... Doc9 will be accessible via the "More Windows..." option.
*
* Doc1 5000
* Doc2 5001
* Doc3 5002
* Doc4 5003
* Doc5 5004
* Doc6 5005
* Doc7 5006
* Doc8 5007
* Doc9 5009
* Doc10 5008
