* refactor: convert Menu and globalShortcut to gin * refactor: convert api::Cookies to gin * refactor: convert View and WebContentsView to gin * refactor: convert WebContents related classes to gin * refactor: convert powerMonitor to gin * refactor: prepare for header change * refactor: remove last uses of mate::EventEmitter * refactor: remove mate::EventEmitter * refactor: move trackable_object to gin_helper * fix: custom converter should not use Handle * fix: no more need to check if icon is empty It was a bug that the Handle<NativeImage> can be non-empty when the image file does not exist. The bug was caused by the converter code writing out the image even when the convertion fails. The bug was work-arounded by adding an additional check, but since the original bug had been fixed, the additional check is no longer needed. * fix: should always set frameId even when callback is null * fix: do not mix gin/mate handles for NativeImage
