shell-global.c: remove a log message about missing 'Categories' key in the desktop file, as this key is not required

main.js: set desktop environment to "GNOME" so that GIO can determine correctly which applications should be shown in the menus.

appDisplay.js: filter out applications that should not be shown in the menus, check if get_executable() for GAppInfo is not null before using it
