Moderation center

Fixes #505 couldn't reproduce #635

- Puts the moderators notes outside the rest of blocks, uses all width available.
- Removes moderation settings for latest news and notes.
- Adds the time stamp to each note. Dunno whats the best place for it so I just put it at the beginning.

I know its a bit hackish, however, I wanted to avoid breaking as less things as possible.

Dunno if the latest news block will be used somewhere else, I just remove it.
