v9 release

Structures now search their entire inventory for fuel instead of only the first slot. This change applies to the mining rig, stirling engine, and nuclear reactor.

You can now use the mouse wheel to change the length of conveyors and the mode of structures before placing, no control clicking needed.

You can now use mouse wheel to change the size of chest inventories.

You can now use shift+e to zoom back.

The function for placing structures next to other structures no longer prioritizes the ore veins over the mining rig.

Cowgirls are no longer affected by conveyor belts.

All items now have shadows when dropped on the ground.

Fixed bug where the upgrade menu showed the wrong version of the backside of the bra when character was facing up.
