[Forums] render webblock html

Hi,

My 2 cents on those HtmlRenderer methods:
   - They were made just to work with ECT and EPA. They may or may not work correctly in any other cases.
   - I don't recommend using them. You should view them as legacy actions that should not be public.

...I'll ask for a deprecated warning on them, since I'm tired of having discussions here about this.

Regards,
João Rosado
