elinks_object: use usrerror if there is no term

Browse Source 
Currently, elinks_alert assumes that smjs_ses is not NULL and crashes if
it is.  Change elinks_alert to check whether smjs_term is NULL, try
get_default_terminal if so, and fall back on printing to stderr using
usrerror if no terminal is found.
