2.8.0

Cool, been trying to find a good reason to do this myself. =)

The predicted distance to enemy is a good use for it, but besides that, every thing I prototype that might make use of this ends up failing pretty hard, and/or being really slow by killing my second wave surf danger cutoff optimization. Which isn't a deal breaker if it gave serious APS gains, but is pretty close to it, and makes it much more painful to test. I recently made another serious pass at "factor in danger of firing situations presented to the enemy" that fell into this category.
