Clean console menus

Description of change

• Re-Created the startup.blend from scratch to avoid 'Error, region type missing in - name' messages. ⚠ May create bugs, I tested the most I could, let's see but keep it mind this might come from the startup.blend
• Changed the tool settings display in the panel, copied from the native Blender panel and removed unused panels.

How to test it

• Use Stax and watch the console
