nwg-shell-config 0.5.44

• Obsolete "Updates" button and scripts removed; those used to deal with user config files, and had been abandoned long time ago;
• tray system update indicator applet and the nwg-system-update script prepared to work with pacman/checkupdates only, and no AUR helpers; they are still capable of using baph or yay, if the user decides to install one;
• fixed, but necessarily simplified detection of longitude and latitude for the user's time zone used by the Night light setting; should hopefully work in most cases.
