* Use a full trace for the AI LoF test.

* That sould stop them from trying to shoot through bulletproof windows and
  other indestructible transparent obstacles.
* Don't abort AI move if they are hurt mid-move.

* It breaks their tactics because the AI won't check that they actually arrived
  at their intended destination before trying to carry out the next actions.
* TODO: This isn't optimal, it would be better if the AI checked for mid-move
  interruptions and choosed an appropiate response, but this shall do for now.
