Increase Fish Sell Prices#1628

At the moment, its barely profitable to sell your fish in the PyroFish Shop, rather players resort to using player ran chest shops at much higher prices ($500 per fish, as opposed to $8) in order to make reliable profit. Increasing the /fish shop sell prices will create more demand for fishing all around, and will inadvertently buff fishing minions (which need a buff desperately)
