I've reverted the missile system to the original one because i didn't have any custom AI that is compatible for the 'missile against missile' doctrine.

The first update for the Type-31 design. Now, General Purpose Missiles & Quick Interdiction Missiles has been set to have engagement range to automate it's operation during missile defense role. This is also useful when the ship is used as enemy/under AI control.

The new missiles doctrine is as follows:

General Purpose Missile:
100 km range, 2 missile launch cap.

Quick Interdiction Missile
40 km range, 4 missile launch cap.
