Update to V3.1 and Tutorial Video

Hi there,

I just added a tutorial video: https://youtu.be/b5NrMyjoilc

And I added the option for a background texture to the HMTL version. Just add a bg_texture.png to the folder and it will be loaded in. Additionally you can now deactivate the visual bot!

Changes:

• Option to deactivate the visual bot
• Option to add background texture to the HTML version

HF and a great day!
