ShowDevTools method generates warnings on Mac OS X Yosemite when launching DevTools window. This seems to cause a crash later on in my app. Here's what Apple documentation states.
NSWindow has never supported clients adding subviews to anything other than the contentView. Some applications would add subviews to the contentView.superview (also known as the border view of the window).
NSWindow will now log when it detects this scenario: "NSWindow warning: adding an unknown subview:".
**Applications doing this will need to fix this problem**, as it prevents new features on 10.10 from working properly. See titlebarAccessoryViewControllers for official API.
