The helper script was also refactored to minimize the amount of callbacks added and the memory used. There's no need to keep callbacks attached for non-active windows, which happened before. Also it should be more efficient and simpler to send info over with just a single DBus call (also if more fields were to be added). Both the script and the helper app will send/print info only if it changed since the previous one. Otherwise we'd keep spamming fullscreen false update when navigating the desktop and so on.
