Jupiter Icy Moons Orbiter 02

This is an update of the JIMO - Jupiter Icy Moons Orbiter from 2003. It is a purely cfg-file-driven addon, and as of today is still flying in Orbiter.

Removed the launch scenario, as the old launch vehicle is no more available
Added a Europa Moon Lander.
The low-poly charm of the early 2000s was left unchanged.
