#9 range ugrade dont show correctly

[Vixis]

After upgrade that increase attack range, explanation in attack command button show always +1.
It seems that in command_type.cpp is misspelling in line 207:

//attack distance

str+= lang.get("AttackDistance")+": "+intToStr(attackSkillType->getAttackRange());

if(totalUpgrade->getAttackRange()!=0){

str+= "+"+intToStr(totalUpgrade->getAttackRange()!=0);

}

str+="\n";

There is unnecessary second !=0.
If we have attack range upgrade, we have always true (+1).
