Sawmill all in one v 17.5.25

A lumberjack that turns fuel into wood is built into this typical sawmill.
After then, this might be used for more production.
Additionally, a pallet manufacturing system is set up.
As an initial incentive, 5,000 gallons of fuel are already included. So get started and build up.

Changelog: V17.5.25.
A solar panel was installed to generate electricity.
