#93 Intercept non-hostile missiles

[Markus Armbruster]

In RL, any missile coming in, if detected, would be
targeted by ABM's. Noone is going to read the
manufacturer or senders label to see if it came from
foe (intentional) or friend (unintentional). A missile
coming inbound is a problem. (RL and EMpire)

I suggest a change that allows abms to react to any
threat. What if a player mistypes a coordinate? Just
cause we are friends doesn't mean that we are stupid
about an icbm, most likely with a warhead.
