+ wheel steering and throttle controls
+ quaternion wrapper (SeleneQuaternion)
* fixed V:GetNormalHeight()
+ V:GetSurfaceRotation() : quat representing "UP", should be changed to north
* V:GetSurfaceRelativeRotation() : now works, but relative to GetSurfaceRotation
* exception reporting from callbacks is now super-verbose
* changed SeleneVector/SeleneQuaternion from "struct" to "class" to avoid similar constructor calls returning same object
* new icon
+ control inputs are now clamped
moved Util to SeleneCore
