Firefly Class Transport 'Serenity' From 'Firefly'

This was another why the hell not builds.
Based on the movie version with some animations thrown in.
The first visual model was a pain as I overran the poly count for display by a fair amount.
In flight sim terms, this meant the visual model wouldn't show up in Flight Sim, AKA invisible.
Took some trimming down but got there.

Sadly I never did make it fly the way I wanted or even scaled it correctly
so just released it as a developers pack for folks to tinker with as they saw fit.
