Panel output font is not saved

[Poobslag]

If I change the Gut settings for a project, the "Panel Output" font is never saved. It always resets back to CourierPrime size 30, which is very big. This matches the contents of the .gut_editor_config.json file:

  "output_font_name": "CourierPrime",
  "output_font_size": 30,

Other settings such as the Runner Window opacity are saved and loaded fine.
