Thanks once more for such a great editor!

_**Intro**_

Working in dark mode in the MacOs system (and probably other systems too) it is annoying with a single application that does not adhere, and that does not have an obvious way of changing to dark mode. It is possible that I have missed how to do this

Changing color theme works. BUT, it is only the text area that changes (all the rest of the GUI is light).

_**Digging around, I found that dark mode is in principle implemented, and that there are indeed two different css:**_

/Applications/Geany.app/Contents/Resources/share/themes/Mojave-light-solid/gtk-3.0/gtk.css /Applications/Geany.app/Contents/Resources/share/themes/Mojave-light-solid/gtk-3.0/gtk-dark.css but I am not aware of a way to tell Geany which one should be active (gtk.css is on by default)

_**What works:**_ It is possible to rename gtk-dark.css to gtk.css, and then Geany looks beatiful in Dark mode.

_**Request:**_ Listen to the system setting, with option to override to dark/light mode from the settings menu. As a last resource (not as good) allow and document a "less hacky" way to change to dark mode, such as a setting in geany.conf

(Tested on Geany 1.36 with GTK+ v3.24.10 and Glib v2.60.6 runtime libraries)
