Subject: [PATCH] Don't return error for blocked MUC messages

If a message stanza is blocked as per XEP-0016 or XEP-0191, return an
error only if the type of the blocked message is "normal" or "chat".
This makes sure users won't be kicked from MUC rooms when blocking other
participants.

Closes #897.
