PocketMatrix

I had to make at least 30/40 changes to Space Treker for WM5 to do an extra 'get display' all over the place.

I used to do this at the start of any function which wrote to the screen but with WM5 it's needed after anything significant/unusual is done. So in each funtion there are 2 or 3 'get display' calls now & it all works.
