Fix drawing creatures in UICreature

I will leave this ugly hack for the time being, but I do encourage to change it later on. The whole "resize" boolean makes no sense since the outfit is resized by the destination rectangle anyway. I believe we should give it a try with a real size of the object defined in dat by the user for creatures bigger than 32x32.

Please keep in mind that we did cut bigger creatures to 48x48 (2*Otc::TILE_PIXELS*0.75f) before as well, so nothing really changed besides ability to properly draw bigger creatures than 64x64 on battlelist.
