Zorb Lua Script Vessel Add-On for OpenOrbiter 2

1. Added a simple magical weightless 10 kN thruster to inject some energy into some bouncy explorations. Uses usual main thruster controls. It is not exactly steerable, but if you are bouncing and tumbling and fire the engines at the right time you can "steer" and explore.
2. Updated the scenarios. Zorb MOOSE scenario mimics the MOOSE concept of an orbital emergency crewmember escape and recovery system. Interesting challenge to perform deorbit burn and reenter without excessive G loads. Bringing the periapsis down into the upper atmosphere ~ 80 km is sufficient to deorbit. Much lower and the Zorb deaccelerates very quickly, with G loads of 9 or more for sustained periods.
3. In atmospheric scenarios drag can quickly and realistically dampen motion. If you want a very bouncy experience, you may wish to disable drag by commenting out the following line in the Config/Vessels/Zorb/Zorb.lua file:
   Code:

   --vi:set_cw({x=1, y=1, z=1, zn=1})

Forgot to include the config file.
