* libnautilus-private/nautilus-program-choosing.c
	(nautilus_launch_application_from_command): Changed the system(3) call to
	launch application from command. Instead use eel_gnome_shell_execute.

	* src/file-manager/fm-directory-view.c (activate_callback):
	Now use newly public NautilusDesktopFile class & nautilus_desktop_file_launch
	to launch the corresponding command.

	* libnautilus-private/nautilus-desktop-file-loader.c:
	* libnautilus-private/nautilus-desktop-file-loader.h:
	Made the NautilusDesktopFile class public. The struct has been moved
	from the source to the header. The nautilus_desktop_file_new method
	is not static any more.

	* libnautilus-private/nautilus-desktop-file-loader.c
	(nautilus_desktop_file_launch):
	Add the locale name taken from the desktop file to display it
	through xalf (launch feedback).
