Add an option to skip moving the pointer away during cycling

Usually cyclefocus moves the pointer to the top left corner of the
screen during cycling to avoid interference from sloppy focus handling.
However, if the user does not use sloppy focus, this pointer movement is
not needed, and can be annoying.  Add an option to disable this pointer
movement.
