1.2.Physics Re-factor - 06/24/19
Removed all Physx and Apex dependencies from the plugin core, now only uses base engine includes.
Re-wrote everything that was possible to do so to be on the new Physics generic interface (some parts of it are incomplete so couldn’t migrate yet)
Added GetPhysicsHandleSettings and SetPhysicsHandleSettings nodes to the controllers, they get/set per axis settings
for the physics handles. Will be expanded to include limits and other goodies in the future.
Fixed a bug where manipulation grips with wrist input were not using the custom angular stiffness settings.
These changes are primarily to prep for supporting Chaos in the future, but also to open up some more settings to users for
more complicated grip constraints.
