Support for icon in titlebar on Windows

[Songtronix]

Right now it is not possible as far as I know to set an Icon on the top left of the titlebar on Windows.

web-view README has a link to winres for that. In short, you have to create a custom build.rs for your app where you set the icon.

@alexislozano im using winres. But as far as I see it only set the icon for the executable so I see it in the explorer. However I want to set the icon in the window title which opens when I start it. I can send you a screenshot of it if needed.

As you can see the console popping up does have the icon. The exe itself does have the icon too. However the window in which I'll do my gui does not have the icon. Instead there only is the default one.

I thing this issue is still opened in web-view : Boscop/web-view#23
