New: Added listener onblur and onfocus on the CPPlatformWindow for updating keyWindow and firstResponder

Previously, when switching from a platformWindow to another platformWindow or to another application, Cappuccino did not behave as Cocoa, Cappuccino still considered that the window was key and main.

Now it works as in cocoa, the platform window lost its focus and is not the keyWindow and mainWindow of the cappuccino application.
