Release Version 0.8.6

Hello again everyone,

This is another smaller update but one that should have the most welcome feature of the tutorial no longer crashing! I did an input mapping change a long time ago that I missed fixing up the tutorial with, and now that should no longer happen.

The other big news is I have moved Tracks into Ren'Py 8 rather than 7. Mostly this shouldn't affect very much but hopefully it means better compatibility in the long run and better stability. The main issue I had with the move was that Ren'Py 8 handles file loading slightly differently and defaults all files to be loaded as byte strings rather than utf-8 strings. This meant that my little parser that lets me write all my scenes in a comfortable format and quickly import them into the game completely broke when it thought it was supposed to be reading text strings but was getting bytes instead. Anyways that was an adventure in finding where Ren'Py's encoding options were.

The last addition here is the start of my attempts to allow for some control customization. These exist in the config_keymap.rpy file for now and you need to be using pygame constants to edit them but they are out of the main files at least. Unfortunately for whatever reason Ren'Py doesn't have the key_code() function which is what I was hoping to use to just let the key mapping be an easily editable text file, but I'll be trying some things as time permits.

Also, I heard that only one key was working in the linux build, I have no current reliable way to test on that or even MacOS so if you encounter problems please, please let me know! 

Thank you all for the continued support!
