More ways to grab closed beta keys ahead of the Droughts patch

Our IndieDB key giveaway was so popular we've had to think of another way to distribute beta keys in time for the new patch! So, we'll have a wave of keys around the release of the new patch, plus we've just started a giveaway on our Twitter, AND we'll have a week of daily mini-challenges with keys to win, starting on Christmas Eve. Woah!
