add disabled buttons, instead of now showing buttons at all when they wont do anything, now show a disabled button instead. this severely breaks compatibility with blackbox themes since there is no good way to automiatically create a disabled button that i can think of, so if they dont exist in the theme you get black and white for the button.
when a window cant be resized, its handle is not removed but its grips are.
change allowing the user to disable individual decorations as that is overkill,
instead allow a toggle through the client.decorate boolean.
