Python 3.10.4 collections fix + added grave (`) key code

I tried the other pull requests and their fixes for python 3.10 didn't work for me. Disclaimer, I had to remove win32con.VK_MEDIA_STOP. It wouldn't work otherwise.

I also had a need to use the grave key in a key-bind so I added that functionality as well. Don't know how well this works for other machines because I didn't use win32con, as they don't have that bound either.

You can safely ignore changes on the readme.

Thank you for fixing the collection error, I fixed it locally and went looking if someone submitted it. I hope it will be merged some time in the future.
