Title: Foros and blogs

Counting
hilos + respuestas = total en foros
&
posts + comentarios = total en blogs.

To do so, we know than foros are those with certain subtipo_id values, and blogs are when blog_id is not null, and we also know that hilos & posts have inicial_id = id (they start the conversation), and respuestas & comentarios have inicial_id pointing to another message (which will be either post or hilo)
