0.0.3 update

Wahoo! 

The main goal of 0.0.3 was to get procedural spaceship generation working. This basically means the main loop is playable: you're spawned in a overworld with some ships of various sizes/strengths. When you fight, a ship is generated. When you clear the ship, you're popped back in the overworld.

This means the goal of the next update is to make what's on the ships more interesting, and start to add variety to the game!

Onwards to 0.0.4!
