  -----------
  changes to rlocus to be compatible with discrete-time systems (#410)

* give correct z-plane damping ratio on mouse click

* auto zoom into unit circle

* show zgrid with lines of constant damping ratio and natural frequency if desired

* sisotool now plots dots instead of a continuous line for discrete-time systems

* fixed spelling of variables in a couple of places
