Compatibility Update. Fixed default upgrade cost(thanks to @e4tern). Fixed Soft Crafting not applying costs. Added Better HMGs - Heavy Machine Guns support by @yakuzadeso.

Supports Mod Settings but it is not needed for mod to work!

Default setup just allows weapon upgrade. Can be edited via manually changing values in UpgradeWeaponsUnlocked.reds or via ModSettings. Has a fix for crashes when Mod Settings is present in mod setup.
Supports 2.0.2.

Fully functional weapon upgrade from common to legendary++

Upgrade to 2.1 compatibility and hopefully a full compatibility fix for Smart Scrapper by DJ_Kovrik

Attempted fix for possible corrupted items, like ones that do not go past 5+ on upgrade or just show up on upgrade list but can't be clicked on(selected).

Added new option - making item iconic on upgrade to ++ and compatibility fix for smarterScrapper. On top of merge with Preem Weaponsmith and option to upgrade to max possible level in one click.
