Trees and rocks!

I’ve just improved the terrain generator with trees and rocks… These can be different (in quantity and image) depending on the type of planet…

It really improves the overall look, and although they’re just cosmetic (no collision detection for now, at least), it also has gameplay impact (for example, jungle planet becomes harder because you can’t see the enemies as clearly).

Still need to tweak the AI a bit (and add the robot spawning as part of the generation of the planet), and then I can move on to the Starmap screen!
