Haha, calm down, I know that this is annoying, but all will be good. 😉
I hated to have to re-implement the event system myself, but it just was not possible to use the original one. It's impossible to combine it with Starling, because it doesn't allow bubbling over anything else than flash.display.DisplayObject classes. I tried really hard -- it's just plain impossible.
At least there's simple fix when you're adding a classic event listener. Just write your event handler like this:
function onEvent(event:Object):void { ... }
Note the use of "Object" instead of "Event". This avoids having to import that classic event package.
As for the naming, we've discussed this for a long time in the forum, but all alternatives suck at least equally. So I decided to keep using the original names in a different package. I can tell you, though, that you'll quickly grow the habit of being more careful with selecting the right imports. After a while, your brain will automatically choose the starling variants. 😉
All in all, sorry for the troubles! But in the end, it's not as critical as it looks at first sight.
