Ignore WS_MINIMIZE and WS_MAXIMIZE in SetWindowLong

[Robert Shearman]

Hi,
According to this URL a number of WS_ flags cannot be changed after the 
window is created (using SetWindowLong):
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/WinUI/WindowsUserInterface/Windowing/Windows/WindowReference/WindowStyles.asp
This patch uses that information and ignores just the WS_MINIMIZE and 
WS_MAXIMIZE styles in SetWindowLong.

Changelog:
Ignore WS_MINIMIZE and WS_MAXIMIZE in SetWindowLong.
