Bugfix 0.3.2b (inventory)

I made a fix for the bag, because for some reason after opening it in-game, it gives a huge error message. 

Finally I figured it out that the bag try to display the quantity of non-stackable items, but these lines were commented out in the code, because I was st*pid and forget to add them back. 

Please start a new game, there's a "SKIP ACT" menu for every new game.

I hope it's alrighty now, have fun testing the new stuffs. :)
