Make AbilityRequiresTargetingActivation use a configurable list

[robojumper]

(Controller Support)

UITacticalHUD_AbilityContainer.AbilityRequiresTargetingActivation does this:

if( ClassIsChildOf(AbilityState.GetMyTemplate().TargetingMethod, class'X2TargetingMethod_Grenade') ||
   ClassIsChildOf(AbilityState.GetMyTemplate().TargetingMethod, class'X2TargetingMethod_Cone') ||
   ClassIsChildOf(AbilityState.GetMyTemplate().TargetingMethod, class'X2TargetingMethod_Line') )
{
	return true;
}

This function indicates that after selecting the ability, you have to press A again to aim the ability, which allows the user to rotate the camera with the buttons that would normally cycle the ability selection.

However, this skips some TargetingMethod -- RocketLauncher, for example is a Grenade, but BlasterLauncher or BlazingPinions isn't. Making this list configurable would allow a more consistent behavior.
