Joystick with Rift and Vive

[johnallen]

forgot to say thanks for this. Got it working after a period of fumbling in vizconnect.

For the record

1. in the 'inputs' section, add a joystick
2. In the Transport section, add a new one and select 'walking'
3. Click the mapping icon for the new walking transport and for each action
   1. If your joystick has a slider, then make sure its in a central position (reading zero) before you continue
   2. from the drop down select joystick (instead of keyboard)
   3. Hold the joystick in the desired position (eg pushed forward) and click the button to the right hand side to assign the input signal
   4. repeat for all the mappings you want to set
   5. Apply and Exit
4. Make the new walking transport the default one
5. in the scene graph on the RHS drag the root of the tree just below the old 'main_transport' and drop it under the new walking transport
6. test it by using the joystick to navigate around the piazza that vizconnect autoloads
7. save your new vizconnect file
