Button in dashboard for new user handoff

[sorenen]

Showing VR quickly to a new user is an ordeal.  

Opening the dashboard should have a button to pass off the headset and have options for full VR intro including IPD adjustment, joystick demo, and then back to the current app or one we choose for them.  

Maybe a checklist for ensuring folks can get help.  Like - Is it blurry? Here’s how to adjust IPD, move headset etc.  

And stationary guardian handoff - seated - just breaks if you want to show someone else.  Should trigger a reset if required.
