Message App UI simplicity

Well, I've started on a largeish improvement.
It works*, but there is still much to do. Just figured I'd post here so someone else doesn't start duplicating my effort.
So far:

• separate screens for messages/call/music/map
  
• scrolling messages, you can scroll down to the next message
  
• left-to-right swipe takes you back
  
• right-to-left on a message shows actions menu
  
  

* With the latest cutting-edge firmware, Bangle.js1 should in theory work, but not tested yet.
