Avoid the 'Roids!

Asteroid collision is now coded. There may be some changes, based on response from Ironduke over in the core coding thread. Additionally, this in no way reflects any line-of-sight code.... i.e. you can definitely still shoot through/past asteroids without any problems.

That said, if you try to fly through one, as per the rules, some dice will be rolled and you'll potentially smash into an asteroid. Also: it really hurts. This work also laid down some of the initial groundwork for flak processing (although not for flak firing).

All of you: pay close attention to ship movement and any anomalies. Teaching it to smash into asteroids involved putting in all the hooks for collisions. The following algorithms were indirectly affected by these changes, and may no longer work (to whatever extent they once did) so look out carefully for bugs in these areas:

1. All ship movement, especially when they're on the same square as anything
2. All missile movement
3. The missile 'chase' algorithm
4. Movement listings in the 'field reports'
5. The ship damage algorithm was extended to do 'raw' damage type; this may have impacted how ships receive damage, but I don't think it will. Watch for shots getting through shields unfairly.

So, who will be the guinea pig to smash into an asteroid? (I have a few other features finally on the books; when they're all in place, I'll probably spawn more ships for this purpose, or start a smaller, new game).
