v1.1 Update

I got a lot of great feedback from the first version, and went back to correct bugs in the code, as well as add a few things that make the gameplay smoother and more interesting.

1) Corrected the "nigiri" bug that was wasn't allowing players to select nigiri from the sushi restaurant.

2) Changed text inputs so they are not case sensitive anymore.

3) Added clear indicators for available choices, and made it clear when a choice is being made.

4) Added several extra choices for things to do.

5) Added secret inputs and easter eggs. They aren't required to beat the game, they're just for fun.

6) Added several hints in the game's text to help savvy players reach the true ending.
