setting up instructions + filenaming correction

[lee2sman]

Hi, I'm new to Python and following along with your tutorial.

Page 1 says to make a file input_handlers but it needs to be input_handlers.py Obviously most will figure it out, but you should probably update that.

You state

In order to follow along with this tutorial, you'll need to follow the instructions on that site for setting up Python and libtcod (Part 1 up until the code starts).

I think you should replace that with actual (simple) directions.

Setup

1. Create a new roguelike directory and change to that folder. mkdir roguelike && cd roguelike
2. Download python-tcod into this directory or git clone https://github.com/libtcod/python-tcod.git
3. Copy arial10x10.png from python-tcod/fonts/libtcod/ into your directory. cp python-tcod/fonts/libtcod/arial10x10.png .
4. Copy libtcodpy.py from python-tcod into your directory. cp python-tcod/libtcodpy.py .
5. You're ready to begin.
