Optimized away some long jumps, by rearranging routines within files, and file order within main.asm. Also added some 'relay' entry points for popular destinations, so that a short jump can go to an existing short jump and then on to the final destination, instead of using a long jump - clearly space over speed optimization. All 'relay's are limited to the UI code, and will not have an impact on IDE operational performance.
