* libnautilus-private/nautilus-global-preferences.c: Added a
	default for the ADD_TO_SESSION preference. This should fix the
	problem where some people don't get any session
	management. Miguel's patch removed the code to set this preference
	in the first time druid so we need to default to TRUE.

	* libnautilus-private/nautilus-file.c:
	(nautilus_file_get_string_attribute_with_default): Used return
	statements to simplify the logic a bit.
