Spring Manager: Spring doesn't react properly + Idea

[miquelcampos]

Feedback from David: issue:

• For unknown reasons, we were unable to get the spring to work as expected on some controllers.

Idea:

• Having a visual cue for the spring would be very useful when debugging. It would help the animators understand better what's going on. A simple icon showing :
  • In which direction the spring is pointing.
  • The scale of the spring rig.
  • visibility switch.
