Flutternoid Improved

Learned a few more things about Flutter Flame development and managed to improve the web performance quite a bit. Should load much faster now when going from title screen into the game. Still starts lagging a bit from time to time. But should be far less by now.

Fixed a few minor bugs along the way.

And I decided to add a level time out after all. For now this will still progress the game. But this way you don’t get stuck. You can of course always replay for a better high score.. :-D
