Cocoa: QMenu refactor.
This change prepares for enabling native menus on OS X. Move code from src/widgets to cocoa: - qcocoaapplicaiton - qcocoaapplicaitondelegate - qcocoamenuloader - qcocoamenu - qmenu_mac - misc helpers to qcocoahelpers Create a QNSApplication and QCocoaApplicationDelegate at application startup. New Lighthouse API: - class QPlatformMenu - class QPlatformMenuBar - QPlatformIntegration::createPlatformMenu() - QPlatformIntegration::createPlatformMenuBar() Platforms that wants a native menu integration subclasses QPlatformMenu[|Bar] and implements the create function. The default implementation returns 0, which causes QMenu to use the standard Qt menus. This API is based on the current native menu abstraction that Mac, Wince and S60 uses in Qt 4. The main difference is that the platform classes are proper standalone classes and not #ifdeffed into QMenuPrivate.
