Support building GTK+3 with Quartz instead of X11
Add configure args conditionally instead of deleting them
Make x11 recommended for gtk+3 thus moving from without-x to without-x11 flag
Allow building librsvg with GTK+3/Quartz (no X11)
Add standard GNOME themes for gtk+3 and for gtk+ (optionally)
Compile GSettings schemas after installing gtk+3
cairo: Enable quartz image surface support
gtk+: Make x11 recommended, add Quartz support
Build Wireshark with GTK+3

Keep providing GTK+ (2) or Qt as an option. Also drop x11 dependency,
gtk+ already depends on it.
