SYNOPSIS
        object find_object(string str)
DESCRIPTION
        Find an object with the object_name str. If the object isn't loaded,
        it will not be found.
EXAMPLE
        object obj;
        obj = find_object("std/thing");
        obj = find_object("std/thing.c");
        obj = find_object("/std/thing");
        obj = find_object("/std/thing.c");
        All four statements are equal.
        obj = find_object("/std/thing#42");
        returns the clone whose object_name is "std/thing#42", if
        it exists.
