Updated README.md

Hiya! I noticed there was a temporary file (README.md~) in the repo. I added a .gitignore so those files won't be saved. Also, I changed the readme a bit. I am obsessive about readme files. Most of my edits on GitHub are readme files...

I really appreciate you putting this in a repo, and I intend to help create a torrent for it when all the art is in, as well. This is one of the best projects I've backed, and I am looking forward to making characters for all the art!

If you need help with git, or GitHub, please feel free to ping me. It isn't as easy as it should be, and I've broken enough repositories to give solid advice. ^_^
