First pass re-balancing of Hard Mode, Hive 1.

General trends:
- Made levels harder from the start.
- Levels get much harder by around 1 minute, emphasizing good multiplier
  maintenance.
- Level scores are lower than previous Gold Scores, but still very high.

Made boss perform special attack a lot more often. Boss is pretty tough
right now.

Since Hard Mode on all hives are unlocked at once, Hive 1 doesn't need to
be much easier than the other hives. Rather, Hive 1 should offer
different styles of gameplay.
