Use XSETTINGS to get theme without a DE

[vincentbernat]

Description

GTK is using XSETTINGS as the primary information for theme, icons and font. It surpasses what's inside the configuration files. DE will advertise the values they have in their own registries to XSETTINGS. Without a DE, users can get XSETTINGS with xsettingsd. It is shipped with dump_xsettings to get the current values.

Unrelated, but without a DE, I doubt the content of gsettings matter much. GTK will not read it by itself (this is not related to GtkSettings). I would remove it. People running a part of a DE (gnome-control-center maybe?) will get XSETTINGS.
