Fast Micro AI: exclude hidden enemies from attacks by default

Browse source 
This is done in this way to keep computational overhead as low as
possible.

Also add an optional key attack_hidden_enemies. This can be used to
attack also hidden enemies; or to speed up the AI a little when no
hidden enemies are present.
