Bug 18415 - Advanced Editor - Rancor - return focus to editor after successful macro

After running a macro we should return focus to the editor screen so
editing can continue from keyboard

To test:
1 - Create a macro
   007=vd cvaizq
2 - Run it and note focus is not on editor
3 - Apply patch
4 - Reload page
5 - Run macro
6 - Note focus is returned to editor
