Subject: [PATCH] Fixed: canBecomeKeyWindow response for auxiliary windows.

Without this fix Cappuccino always returned YES for `canBecomeKeyWindow` for every window. But in Cocoa, only "standard" windows with a title bar and/or resizing return YES.

With this fix Cappuccino better matches Cocoa's behaviour.
