... the python console.
It was using "selected text", which is most often inverted color (close
if not identical to the background color). As a consequence, it made
stdout output unreadable by default, forcing themes to always define a
style for the python console. Using "normal text" is a much better
choice to default to something readable from a parent style.
As a consequence, I also removed "python-fu-console" styling from the
System theme, where there should be as few theming as possible.
s/gtk-application-prefer-gimp-dark-theme/gtk-application-prefer-dark-theme/
I'm actually not sure if this property is supposed to be in the gtkrc
file. It looks like it is available only from GTK+3, and isn't it more
of an application settings in order to select the right theme variant,
rather than a specific theme settings?
Anyway let's at least set the right property name.
