Assets should provide a way to register listener

[GoogleCodeExporter]

It would be nice if Assets was implementing the same "observable" facilities as 
AssetWatcher, so that you can easily add a listener to listen for Done or Error 
event.

Something like:
assets().Done(new Listener() {
    public void done() {
        startGame();
    }
    public void error(Throwable e) {
        ...
    }
})

+1, but I would call it setListener or addListener.

I would even deprecate isDone because it causes programmer to ignore errors 
that can happen during loading.

Why is it hard to create an asset watcher and add your assets to it? You could 
even create a facade for Assets which had a built in watcher and load your 
assets via that.

I'd rather not make the Assets API bigger just to support this one, not very 
common, use case. Most games will load and watch assets on a more fine grained 
basis than just "I load all my assets once at the beginning of the game and 
then never care about watching assets again."

I just created another quite similar issue. If desired I could contribute an 
updated AssetWatcher that also uses the correct Callbacks and makes sure not to 
break existing code by adding stuff to the AssetWatcher itself instead of 
changing the Listener (attached).
