double_expansion_target replace

[jzy-chitong56]

When the attack target is double_expansion_target , CheckDoubleExpansionsClaimedInArea should not be replaced , and double_expansion_target can not IsUnitHidden

  if double_expansion_target != null and IsTargetGood(double_expansion_target, 10) then
    call Trace("Double Expansion Attack")
    call SetAllianceTargetIfLeadAndChat(double_expansion_target, C_Ally)
    call FormGroupAM(3)
    call AttackMoveKillAAM(double_expansion_target)
    call ClearAllianceTarget(double_expansion_target)
    if not UnitAlive(double_expansion_target) then
      set double_expansion_target = null
    endif
    return
  endif

There is a possibility that if an ally builds a building near the Town without upgrading or expanding, the AI will kill the base and must be forced to reserve a Town or mine for the AI , And I don't think it's necessary for the undead and the dark night to carry out the job of killing, because they may have already occupied the gold mine
Additionally, the Trace of CheckDoubleExpansion is not accurate
In the end, the entire feature created too many unit groups

I tried to make corrections

This was designed this way so if player prefers the location, AI will sacrifice base himself.
