Day 2: still on the skeleton

Iv hashed out something I think will handle all of the games likely directions. It almost feels like Ive spent too much time working on the architectural details but at least itll be far cleaner than my last attempt which was the messiest python code Iv ever seen.

Orbits are working well, I have the concept of planets and manoeuvrable ships and collisions are sorted. Getting planet labels in were the final straw for me today -they slowly creep off the screen and into infinity -Ill take care of that one tommorow.
