2016-10-02: v. 0.5.1.3

- inert dolls and voodoo dolls can now be stacked; this change should apply to existing ones too

- reorganized a lot of crafting recipes to enable crafting stacks of items from the Recipes page of the crafting window; works with existing saves
# removed 'Quill' from recipe list because you need that recipe exactly how many times in the game ? once ! and not even 'once' might be required
# removed nine inch nails from 2 keys from the recipe list because it's too dangerous to craft them from the recipes page
# removed all crafted skillbooks from recipe list because they only blow up the list with little to no gain gain

- massively reduced the weight of grain sacks because an (almost) empty grain sack can not have the same weight as a full oil barrel, it's ridiculous ;-)

- recipe changes:
# broken bottles can now be created with both Crafter and Blacksmith hammer

- reduced the requirements for a lot of crafting recipes (works with existing saves)
# iron bar + crafter knife: 10 arrowheads -> Crafting 6 to 3
# arrow + tong: arrowhead -> requirements removed (means the worthless arrow that you get when you combine a blank arrowhead with an arrow shaft)
# arrowhead + new oven: fire arrowhead -> Crafting 6 to 5
# water arrowhead + bluegill mushroom; freezing arrowhead -> Crafting 6 to 5
# metal/plate scraps + crafter hammer: empty cylinder/grenade -> Crafting 6 to 4
## sorry, cannot enable crafting them with the blacksmith hammer, because it is used for armor/bracer crafting with those ingredients already
# oven + empty cup/mug/lab bottle/plate/broken bottle/vial: empty bottle -> Crafting 6 to 4
# soap + stack of plates: 25/50 plates -> Crafting 6 to 2
# blacksmith axe + large iron/steel bar: 2 iron/steel bars -> Blacksmithing 4 to 2
# metal scraps + metal scraps: iron bar -> Blacksmithing 4 to 2
# scale scraps + scale scraps: plate scraps -> Blacksmithing 4 to 2
# distiller + (large) steel bar: (large) iron bar -> Blacksmithing 6 to 5
# oil barrel + wood scraps: inert voodoo doll -> Crafting 6 to 1
# magic paper knife + scroll: empty scroll -> Crafting 6 to 5
