The icon delegate was not listening for mouse events -- thanks for catching this. I've restored the `AWTTrayIconView` thing (so that it can handle mouse events) and made it inherit from `NSStatusBarButton` (so that icon painting is delegated to MacOS). The fix is less verbose now. I've also renamed the property `apple.awt.enableTemplateImages` and added an `@implnote` as discussed in the CSR.

Can we consider the CSR approved btw?
