[Work in Progress] FsPassengers for Prepar3D v4 (64 bits version)

[RioPilot]

Appreciate the progress and the frequent updates, Dan.

I find it hilarious how everyone has been begging for an updated FSPassengers for v4, and now that it will finally happen, people keep piling on requests to implement before it's release.

I say let's get a solid working product for v4 sooner, and worry about the intricate updates later on.
