[gtk+] Parse a per-theme settings.ini file

[Matthias Clasen <matthiasc src gnome org>]

commit 55015693541003a765d3d1bb9bc2fbb8a2c0ff34

    Parse a per-theme settings.ini file
    
    This lets themes override settings values again. We are using
    the same priority that was used from the rc file parser, so things
    are largely unchanged, relative to other settings sources.
