Title: cinnamon settings: read backgrounds from GNOME directory as well

GNOME installs the following XML files, which can be used in cinnamon settings:
/usr/share/gnome-background-properties/adwaita.xml
/usr/share/gnome-background-properties/gnome-backgrounds.xml

Read these files in addition to cinnamon backgrounds.
