Weight Reduction Kits 1.9

Going back after one and a half years.
- Added compatibility for Wendover, Bastion, Wigeon and Scintilla.
- Updated jbeams.
- Readjusted stats and values.
- Removed weight increasing/reinforcing parts. They were really gimmicky in hindsight and just bloated the mod. Other mods exist that do it better. I recommend the indestructible mod or the global edits mod if you like that.
