PostJam bug fixes!

Ahoy!

- Sailors can now properly use Persimmons as food, in dire conditions of course!

- Rat no longer gives you dollars (what would you do with them anyway?)

- Boxes images on Upgrade button at the port and your collected treasures chest in the lower right corner are no longer wrong

- Fixed messages like "you've met fearsome Pirates2", we all love DND, but these were over the top

- Some fullscreen fixes for your cool widescreen screens!
