[Harkonnen] [0.15.18] Sunken window border style on Windows

[Archomeda]

The window of Factorio (on Windows) has a slight issue that it shows a 1 or 2 pixel border around the window. When it's maximized, it's easily noticeable compared to other applications that run maximized.

Following what I read on reddit, I've tried it myself as well.
Basically, Factorio has the extended window style WS_EX_CLIENTEDGE enabled. According to the Microsoft MSDN this causes the window to have a sunken edge. When this style is removed from the window, the issue is solved.

Please take a look at the screenshot examples.

I'm not sure if you guys call this a bug, but I'm sometimes annoyed by that white border around a maximized window. It would be nice if you can resolve this natively.
