* apply design changes for the keybindings (LP: #878820, #891757, #751050), debian/patches/ubuntu_config.patch: - Control + Alt + KP_5: don't center, used for toggling maximize state by core - Remove Control + Alt + KP_0 to not maximize, (used to minimize in core) - Super + Left, Right key to semi maximize and stack on left or right - Remove zoom in/out/box (like in oneiric and before). Those should be enabled in g-c-c with the a11y tools.
