src: switch to preferring gtk dark theme

Browse Source 
This enables the app to use the dark theme when running in environments
where a dark theme is available.

This is not done in Windows because the dark theme looks quite odd when
run on older versions of Windows where GTK can't replace the titlebars
by default.
