find_object() - find an object by file name

object find_object( string str );
object find_object( string str, int flag );

Find the object with the file name <str>. If the object is a cloned
object, then it can be found using the file name which would by
returned if file_name() was called with it as the argument.

If 'flag' is 1, this function has the same effect as 'load_object'.
