[PATCH v3] user32: Add MOUSEHOOKSTRUCTEX to fix mouse wheel support for JA2 1.13 and other apps which use it

[Kira Backes]

Hello @André and @Nikolay,

please note that I defined the struct this exact way because of this
MSDN article:
https://msdn.microsoft.com/en-us/library/windows/desktop/ms644969%28v=vs.85%29.aspx

So if you think it's a bad idea to follow the definition of the MSDN
article then please tell me what I should change so I can improve the
patch.

kind regards, Kira
