Lots of Optimizing

So the past week I've really been working on improving code across the board. I've re-written the unit movement code. This has stopped the space marines from sometimes randomly vanishing off into space when they collide with a partially closing door etc. I've included an update to my previous list of known issues from Alpha 1 and whether or not they've been fixed.

1. "Return to Game" button on Escape Menu crashes game.

2. Credits not always displaying.

3. Escape Menu covered by Station Walls

4. Various problems with Vacuum "spread".

5. Marines occasionally vanish to up left-hand corner.

6. Doors will get stuck if a unit blocks them on closing.

7. Marine shooting image occasionally faces the wrong direction.

8. Zombie Survival Version (Kickstarter Stretch-Goal)

The door issue should hopefully be fixed by today. As I've said in a previous post I'm also hoping to make the shooting AI work a little better. Now that I've fixed the movement AI the shooting shouldn't be too much of an issue. I'm also hoping to tweak the spawn rate of random events in the game to make it a much faster tempo.
