Based on No-Title theme by jeansch (http://gnome-look.org/content/show.php/No-Title?content=93438). Titlebars are not really useful! Especially on 1280x800 or less screens :)

This theme fits any GTK theme using its colors. It is a bit thiner than No-Title and maximized windows have reduced decorations. I left some decoration though cause on some GTK themes window could blend with the top or the bottom panel. If you want to get rid of all decorations in maximized state, you may change all non-zero numbers to zero in frame_geometry "maximized" section.
