Kraken tweaks and fixes

CHANGES:
- Island now doesn't load, when there are active krakens, to reduce lag.
- Slightly increased biter swimming speed during kraken fight. This should reduce the chance for biters to get stuck on the ship edge.
- Fixed biters swimming faster with multiple active krakens.
- Fixed biters stopping swimming towards ship when kraken dies.
