Subject: [PATCH] User 'data' folder #5564

Bonsai now creates a user data folder that allows you overriding Bonsai data files. E.g. you can put you own `default.css` as `data/assets/default.css` in that folder and it will override the `default.css` Bonsai is using for the drawings. Previously you could have change internal `default.css` but Bonsai would always restore the original one on every update / reinstallation.

You can also store your .ifc files in data/libraries or data/templates and Bonsai will ensure they're loaded and you won't need to worry about Bonsai removing them later.

E.g. on Windows this path is `C:\Users\xxx\AppData\Roaming\bonsai\bonsai\data`/

You can also find path in the preferences - https://i.imgur.com/kwMc0JU.png
