Running Shoes, new readme, Munchlax

This adds a readme with credits so far. Make sure to keep this updated so everyone knows what is and isn't done!

We also get the Running Shoes feature from the tutorial, finally making debugging bearable given how laggy Crystal's overworld can be at times.

Oh, and Munchlax.
