<pre>Disable activity reply threading if WP comment threading is disabled

In <a href="http://buddypress.trac.wordpress.org/changeset/8201">r8201</a>, BP adopted WP's thread_comments_depth setting for its own activity
reply threading. See <a href="http://buddypress.trac.wordpress.org/ticket/2768">#2768</a>. However, the thread_comments toggle was not
respected. The current changeset adds support for thread_comments, so that
disabling WP comment threading will also enable nested activity comments
(though the top level of comments will still be allowed).

Fixes <a href="http://buddypress.trac.wordpress.org/ticket/5562">#5562</a></pre>
