Release V4.1.0

Changelog

• Fix for helicopters spawning with more fuel than default, thanks for @WheteThunger (WhiteThunder). (Minor version increase is because I consider this a feature more than a fix)
• Pretty sure I fixed GetStackSize errors, let me know if I didn't, wasn't able to reproduce after the change.
• Fix for items like coal and some construction items from stacking. Might make container stacking more reliable as well.
