First Kettuloch update

This update corrects all of the typos pointed out to me by early players, along with a bunch that nobody noticed.

It also fixes the bug the prevented the description box from displaying when you've spent over 70 turns in the dungeon.

Additionally, I've added one more ending (Follow the same steps as you used to find the secret endings, but choose option 1 for your body), but it's probably not worth replaying the game for that, haha.
