[Feature Request] Support macOS Dark Mode

[machawk1]

macOS introduced "Dark mode" for applications. Some users may start to use this option as their default and it appears that WebRecorder Player 1.6.1 does not yet support this. This is understandable, given the newness of the feature in the OS.

With Dark Mode Enabled (via System Preferences > Appearance > Dark):

macOS Preview (built into OS)
Fantastical (3rd Party software)
WebRecorder Player 1.6.1 (no difference)
