[dev] Agora usability patch

[Chuck Hagenbuch]

Quoting Duck <duck at obala.net>:

> Message and flat view had nearly the same functionality. The only difference
> was that the flat view shows bodies, and flat view didn't allow the to
> directly post a replay. I combined the two to not have a code duplication,
> and allow posting a replay directly in flat view. The thread_view_bodies
> preference is extended to allow not just thread or flat view, but event flat
> view with indents.
>
> Other changes:
> - Produce a query less by allowing replyMessage() to accept an message array
> already retrieved in thread view.
> - add pager in thread view
> - add pref option to sort threads by number of posts
> - allow to post a message directly even from flat view
> - Fix sql syntax in agora_forum::search()
> - Fix page titles in message view
> - Don't even load identities if avantars are disabled in message view

Committed, thanks.
