3D Physics and Other Stuff

-=-=-=-=-=-=-=-=-=-=-=-=-=

-New Vehicle (Based on Bullet's RaycastVehicle) - Vehiclebody/VehicleWheel. Demo will come soon, old vehicle (CarBody) will go away soon too.
-A lot of fixes to the 3D physics engine
-Added KinematicBody with demo
-Fixed the space query API for 2D (demo will come soon). 3D is WIP.
-Fixed long-standing bug with body_enter/body_exit for Area and Area2D
-Performance variables now includes physics (active bodies, collision pairs and islands)
-Ability to see what's inside of instanced scenes!
-Fixed Blend Shapes (no bs+skeleton yet)
-Added an Android JavaClassWrapper singleton for using Android native classes directly from GDScript. This is very Alpha!
