Fixes and additions

## Major fixes

- Solved **most** render bugs
- **Chipset slot** in the GUI is a **fake slot** now ( **Temporary** ). You **can't** take or put a chipset in there. **Use the rightclick** function on the extension for that.
- Removed unused **imports**

## Chipset Additions

- Chipsets can be **changed / added / removed** by the **slot** in the GUI now aswell
- **Changing** a chipset through **rightclick** will give the **correct old** chipset back
