Fix/Patch [TFS 1.x] Monster Skulls

[Sitrene]

This fixes skulls not appearing on monsters for some versions of TFS. (Nekiro's Downgrade personally). I saw many threads about this with no fixes.

Credits @zbizu for walking me through this.

In protocolgame.cpp AddCreature() method:

msg.addByte(player->getSkullClient(otherPlayer));

Replace with:

msg.addByte(creature->getSkullClient(creature));

In player.cpp getSkullClient method:

    if (!player || player->getSkull() != SKULL_NONE) {
        return Creature::getSkullClient(creature);
    }

Replace with:

    if (!player || creature->getSkull() != SKULL_NONE) {
        return Creature::getSkullClient(creature);
    }
