add new sort order, and a way to go back to old order

[nicholsk18]

I thought this might be useful for others as well. Our team wants to see all message, but they like to see newest messages first. Radio buttons looked to be the easiest so I also added default option. I know I skipped the place where the messages actually get expended, but since 2 will also equal true figured it be fine. Let me know if I need to adjust anything

Sure! This seems perfectly reasonable. I'll get it merged. 😀

Hey @jstanden any update on when this will make it in to production? Thanks!

I'm interested in this change as well! :)
