- fixed wrong crafting output

- changed Light Spears to use a modified version of the spear stab used by 2 handed spears. This should make them different from shortswords. The change however might break existing Light Spears as starbound fails to update them, sorry about that
- added crafting recipes to enable crafting of Light Spears for the cost of existing one handed weapons. Visuals of crafted versions are currently randomized
