"DarkStalker" level now makes dark bubbles even after the player loses. Player can no longer grab bubbles below the bottom of the screen -- before, it was too easy to button-mash your way through Newspaper and Edgehog. Added buzzing noise when you try to grab an illegal bubble.
Added new level "Moustache".  Slightly relaxed "no grabbing below well" rule, and changed behavior where timer would sometimes count past 0:00 if you kept a combo going at the end of a level.
