Separated client- and server-side features into seperate root folders. Since Stadia Avatar now has two versions (Userscript and Chrome extension).
Added core extension functionality.
Created a page constructor for extension popup. High probability that I will create a seperate repo for this feature, as it's pretty neat and very useful for future extensions.
The bot userscript is now fully operational, the only thing left to do is to make it send the actual payload we need for the endpoint.
Added setup for MySQL database.
Added DB interface with a concept-stage set/update endpoint.
