v3.2.0: reworked thrown weapons to work in 'sets':

- sets are upgraded/enchanted/etc. as a unit, default size of 3
- upgrading completely repairs a set
- durability boost per upgrade down to 1.5x from 3x
- Internal buff added to prevent upgrade repair duplication exploits
- lots of effects that apply to melee weapons now apply to thrown: identification, enchants, curses, etc.
- liquid metal recipe adjusted (liquid metal itself still needs changes)
- Huntress ID talent changed now that thrown weapons are IDable
- darts effectively unchanged, they all belong to the same set, still not upgradeable
- no balance changes to accomodate this yet, tbd.
