This PR fixes several issues with sliders in the preferences dialog:
The fix simply uses a different style sheet for these sliders, that fixes all these issues (the look is based on the sliders as can be found in the macOS system settings).
The PR also includes obj-c code to check if macOS is set up to use dark or light appearance, and a different style sheet is used accordingly.
This is a very non-invasive fix so I don't see any risk of regression.
