Updated to v1.01 - User Experience improvements!

Several improvements to the user experience have been made, based on watching several people play the game recently:

1. If a ball is shot directly into the walls/floor outside the white play area, it is automatically loaded back into the gun. This way inadvertent shots fired while figuring out the game don't cause the levels to advance and the player to lose.
2. Shooting the buttons on the menu directly will trigger them. It was found to be more intuitive to shoot the buttons than to tap them with the gun or paddle. The buttons only trigger if shot directly... they do not trigger if a ball hits them after bouncing out of the play area.
3. Balls now make a small visual burst when hitting outside the play area, so it's more obvious visually that they are gone intentionally.
4. Added an option to the Audio menu to switch between speakers and headphones. Previously, positional audio only worked properly with headphone on. Now, if it is set to speaker mode, the positional audio should sound approximately correct when using surround sound speakers instead of headphones. Headphones is still the default setting.
5. Music volume and speaker settings are now saved between play sessions, so they don't have to be reset each time. Hope this helps your enjoyment of the game, and don't hesitate to post bug reports or feature requests here in the community. Thanks!
