added reverse chronological sorting to Activities....HOWEVER

Doesn't work.  I think the paging system is messed up.  I also don't understand why the change that removed the display text from the Activity document.  It was fine there.   A little verbose maybe but quite convenient and fast and less complicated code.

Please comment back to me about this tx.
