Add constant arraylist access modifiers

[hhaslam11]

For example, Ach.checkLearning():

    for (int i = 0; i < Weapon.arrayWeapon.size(); i++) {
        if (!Weapon.arrayWeapon.get(i).viewedAbout()) return;
    }

    for (int i = 0; i < Enemy.arrayEnemy.size(); i++) {
        if (!Enemy.arrayEnemy.get(i).viewedAbout()) return;
    }

    for (int i = 0; i < Armour.getArmours().size(); i++) {
        if (!Armour.getArmours().get(i).getViewed()) return;
    }

    for (int i = 0; i < Food.arrayFood.size(); i++) {
        if (!Food.arrayFood.get(i).viewedAbout()) return;
    }

Compare the third for loop (armour) to the rest.
