Mixed weapon range problem

[Kamo]

It would be kinda cool to allow the AI to fire or not certain weapons by range.

I found out that if I put a pair of 18 range cannons and a pair of 6 range chainguns on a station, the station wouldn't fire at enemies until they approach at 6 km, and removing the chainguns make 'em fire again at 18 km.

It's silly, and even more with ships equipped with the odd 0.6 range Salvage Beam :(.
