closes #6759

-moved user.blocks.filter from unread controller to getUnreadTopics so
topics are filtered at other places this function is called
- when a new post is made do not send it to uids that have blocked the
poster
- update getUnreadTids so it does not return topics that have new posts
from blocked users
- update hasReadTopics so it does not return false data if topic has new
posts from blocked users
