Fixed bug 8232 (Trash.gmc and home directory link files made by
	gmc show on Desktop):

	* libnautilus-extensions/nautilus-file.c:
	(nautilus_file_should_show): Moved special case for gmc files in
	here.
	(filter_hidden_and_backup_partition_callback): Removed special
	case for gmc files, since it's now in the lower level. Also fixed
	code that was casting a pointer to an int without using
	GPOINTER_TO_INT.

	* src/nautilus-application.c: Fix typo.
