Fixes and other

So, after submitting my game I discovered what I thought was bugs in the AI code - that later proved to simply be missing calls to Math.Floor to convert world coordinates into tile coordinates. This caused the fish to simply never reach their target tiles when feeding - if the target tiles happened to have negative coordinates.

The thing you learn.

Well, I also added some interpolations to water tile colors, AI Scores, added a sail, a wind indicator, and of course saving of high scores.
