	* configure.ac:
	Add --without-libgnome, check for libgnome and libgnomeui
	separately, and add them to the symbols as required.

	* libdocument/ev-file-helpers.c:
	When building without libgnome, use g_get_user_config_dir instead
	of gnome_user_dir_get.

	* shell/ev-application.c:
	When building without libgnome, don't use session management.

	* shell/main.c:
	When building without libgnome, don't use GnomeProgram or
	initialise the authentication manager.

	This fixes #328842.
