Prototype - V0.03 patch

Patch notes for V0.03 build:

- Updated AI logic for better avoidance. Bots will still get stuck between enemies, but that is intended.

- Updated random generation of planets and added framework for decoration objects to be added (example on Alpha 1 planet)

- Major change on Engine System. Will now allow to take off on single power unit allocated. However, the more power given to engines, the quicker the ship can launch. Bots can be left behind if they have not reached the ship upon takeoff.
