atreply (maybe also hashtags?) Classes

[SGr33n]

Hi people :)

I just realized that maybe atreply hrefs could have a class? The best format, in my opinion could be:

<a href="#" class="atreply"><s>@</s>sgr33n</a>

It took me a while to track down the function where we do this, so: bp_activity_at_name_filter().

I think the suggestion is fine. Let's call the class bp-suggestions-mention, as one day, we're likely to have other types of @mentions (think perhaps cross-posting to groups, or hashtags) and it would nice to name these things in the same pattern.

For legacy reasons which probably need addressing sometime, we store the at-mentions expanded in the DB (i.e. linked in anchor tags). So adding the class here won't affect existing activity content, only new content. But, it'll provide for future consistency, and if/when we switch to storing the at-mention name in the DB rather than the link, the fix will already be there.
