find_object() - find an object by file name

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

Find the object with the file name 'str',  which can reference a cloned
object by using the file name format returned by file_name().

If 'flag' is 1, find_object() will behave like load_object().

find_object() returns the loaded object if it can be located (or loaded
when 'flag' is 1), otherwise the value 0 will be returned.
