AI melee weapons support

[tmedanovic]

Hi, first of all, great work!

Do you have any tips for implementing close combat? I spent few hours looking at your code. It slightly more complex then I used to work with.

Would it be correct to check for overlapping in here:

void AShooterAIController::HandleSight(AActor* UpdatedActor, FAIStimulus Stimulus) { ... Fight(); ... }

Thanks
