Title: Allow the velocity to be a vector

Hi, in #145 it was noted that velocity doesn't default to the orbital velocity vector. This patch should do the trick: `VELOCITY` is then the orbital vector but additionally stores the surface vector.

**DISCLAIMER**: As my computer is not set up for development and testing C#, I'm not sure that this code works as promised. (I really have to set up my computer for developing KSP plugins)
