Need to not use native Alerts for uncaught errors in the web pages

We need to get the console working, and send the errors there. If there's an error in any scripts that runs in the animation loop, it's impossible to do anything except kill argon (since a new error pops up as soon as you kill the previous one).

If we want an alert, we should implement it with some other technique so it doesn't take over the app. It should be tied to the page, not the app.
