VR Expansion Plugin

Pushed a new commit to the plugin and template today.

Template changes



 Stable enough for beta release on the car (is not entirely complete, please ignore half done parts)  
 Made the steering wheel of the car a lever now instead of a dial and added a new mesh for it  Added new template level section specifically for playing with the car  

Plugin changes



Fixed Simple characters overriding the RequestedVelocity of the base FSavedMovement class (fixes client side navigation with simple char).  
Added a check in the VRLever to help prevent it flipping sides when over rotating.

Changed the parent relative attachment component so that it sets relative space instead of world space position now.    
World space was a holdover for when it was directly attached to the camera, not only is it not needed anymore, but it also can result in the incorrect behavior.

Added a default lerp to the snap setting for the ParentRelativeComponent  
Can be turned off and speed can be adjusted.
