MDL-48148 mod_forum: Use the standard forum reply subject as default

When a user replies by e-mail, the course name has been included in the
original e-mail. As a result, the reply subject becomes longer and longer.

In cases whether either:
* the discussion name; or
* the replied-to-post subject

is present in the mail subject, the standard reply subject is instead used.
