Change window-clone-border and window-close style
requested to merge Feichtmeier/gnome-shell:ShellTheme_window_clone_border_and_close_button into master
.window-close: simplify the normal, hover and close circle by a blue, lighter blue and darker blue solid disk -> also add a slight box-shadow to make the close button look a little bit leveled up from the clone border
.window-clone-border: use a milky, transparent white border for the hover effect of the the border
similar to the hover effect currently in master for hovering above apps in the app grid:
Hover (lighter blue):
Active (darker blue):
