Update for version 1.3.

Updated to v1.2

Fixed warning: Fixed some warning about some Texture2D complaint from Rimworld. This however shouldn't be a problem but the Rimworld Devs apparently added this as a warning... So okay fine, I removed it.

- Added default presets.
- Added 2 presets that you can use to save & load settings.
- Added sliders (now you have both fields and sliders).
- Refactoring.

Note: Your old settings will be gone.
