[FIX] maillib: Zend doesn't parse "Name <email@example.com>" style addresses for from or reply-to (any more?), so it needs the name supplied separately. Also Zend adds wraps message-id with < and > so remove from our call.

[FIX] forums: Several fixes and improvements for process_inbound_mail for forums (was quite broken).
Use the html part if there's no text part available, and use the root 'body' section as a last resort (it's usually the source)
Ignore error report emails (needs more testing and possibly logging)
Try and find the message referred to in in-reply-to and use that topic if there is one
Also some code tidying and comments added
