<h3>Log Message</h3>
<pre>Correct phpdoc for `bp_activity_recurse_comment_count()` and `bp_activity_get_comment_count()`. Also formally deprecate `$args` in `bp_activity_get_comment_count()` and add filter at the end of `bp_activity_recurse_comment_count()` so it can be manipulated by third party plugins.</pre>
